Traffic Control Power Supply

Jasper Electronics is a leader in traffic control power supplies designing and manufacturing. Compared to legacy supplies, Jasper’s traffic control units are more compact, more lightweight, and more efficient. They are also California, New York, Georgia, Alabama, Colorado, and other’s primary choice for their state departments of transportation. These power supplies come with 5-48 VDC and 70-400 Watts and are available to be used in new, existing, and custom configurations. They are highly reliable and have both single and multiple outputs.

PDAs – Model PDA2-LS

We are showing off our custom Power Distribution Assembly (PDA), the model PDA2-LS, which manages the intake of AC power and distributes AC and DC power to a traffic control cabinet’s circuit. It can be used in configurations that are both either new and existing.

This assembly is powered by three AC circuits that are obtained from the Service Panel Assembly; each being terminated at a 15 Amp circuit breaker. From the front panel, you can access the NEMA type 5-15R GFCI duplex receptacle, which is powered by “AC+ Equip”. In the rear panel, there is an “ER2”, which is a type 5-15R non-GFCI receptacle. The majority of the circuitry both within and connected to the assembly is powered by “+AC RAW”. An EDCO Model SHA-1250 ITS (or equal) surge protector and EMI filter allows “+AC CLEAN” to pass through.

There are two user-accessible slots that can be used to install a Model 204 Flasher Unit in each, thereby providing four signal drives that alternate. The power on these models is controlled on the front panel using a two-pole 20 Amp circuit breaker. Six 10 Amp signal circuit breakers are wired to terminal blocks located in the rear cover, and those are then wired to the outer Output File Assembly.

The PDA2-LS is compact but has room for customization, and in 336LS and 346LX cabinets, it has room for a drawer shelf for laptop support.

Compact PCI Power Supplies

We have both AC and DC input models available for our compact PCI power supplies, with options from 175-500 W. Our AC/DC has 90-264 VAC input, and our DC/DC has 18-72 VDC input.

They have hot swap and Oring diodes N+1 operation and use a standard 47-pin output connector, with some models that have 32 & 38-pin options. For 3.3, 5, and +12V rails, they also feature current sharing.

They also feature full power to 50C ambient with a derating of 70C and >0.99 line Power Factor Corrected typically at AC 115V. We have AC (90-264 VAC) and DC of the single, dual, and individual unit varieties. These power supplies units can also be ruggedized.

GPAD-Series Convection/Conduction Cooled Power Supplies

Are you tired of having to periodically clean your fans, worrying about fan failure, dealing with irritating fan noises, and want to improve your MTBF performance in your cooling power supplies? We eliminate the need for fans entirely with our GPAD-Series convection/conduction-cooled power supplies! These models can operate in temperatures -20°C to +70°C, and feature a moisture-proof design that is flame retardant.

RC Snubber – Transformer Protection Circuit Components

Circuit Diagram RC Snubber per Phase

Resistor-Capacitor (RC) transformer protection snubber circuits safeguard medium voltage distribution transformers against transient overvoltages, which minimizes failures. RC snubber circuits are crucial for the protection of dry-type distribution transformers, especially when close-coupled to vacuum switching devices.

These RC networks, consisting of RC configurations, are installed on the high voltage windings of transformers to mitigate transient overvoltages and dv/dt events. They are primarily employed in three-phase distribution transformers.

Medium Voltage RC Snubbers counteract damage from events such as:

  1. Switching on an unloaded or lightly loaded transformer.
  2. Transient recovery voltages (TRV) during transformer de-energization.
  3. Current chopping (CC).

The snubber circuit comprises three fundamental medium voltage components per phase:

  1. Damping resistors
  2. Surge capacitors
  3. Fuses

Hill Tech can assist you with both your fuses and damping resistor requirements for RC snubber circuits.

RC Snubber Circuit Components from Hill Tech

DAMPING RESISTORS: These non-inductive tubular power resistors, constructed of either carbon ceramic or silicon glass, are inherently non-inductive and can handle large surge energies with high continuous power ratings. They feature an anti-track coating and sufficient length, making them suitable for medium voltage applications.

Rod and Tube Carbon Ceramic Resistors
Rod & Tube Carbon Ceramic Resistors

Depending on the surge energy and continuous power rating required by the resistor two different technologies should be considered either silicon glass resistor or carbon ceramic resistor type. Silicon-Glass Tube Resistors are rated up to 330kJ at 1000W and 30kV, whereas carbon ceramic tube resistors are rated up to 119kJ at 225W and 120kV.  Contact Hill Tech with those requirements for the best technical solutions.

Silicon Glass Tube Resistors
Silicon Glass Tube Resistors

Various mounting end-caps and clips are available for mounting these resistors.

FUSES: Fuses play a crucial role in preventing the destruction of the snubber circuit. If the fuses fail to operate, the resistors effectively act as fuses, resulting in the loss of protection provided by the snubber circuit.

High Voltage Fuse
High Voltage Fuse

High-speed, current-limiting fuses, such as the new HHA-BC series, are specifically designed for optimal performance in capacitor circuits. They are suitable for indoor and outdoor usage in the North American market. The voltage rating of the HHA-BC capacitor fuse matches or exceeds the maximum open circuit voltage of the system, ensuring effective operation during fault conditions.

The HHA-BC capacitor fuse is available in various voltage ratings, including 4.8kV, 5.5kV, 7.2kV, 8.3kV, 15.5kV, and 23kV. We offer different mounting styles, such as threaded/tapped ends (1/2” UNC or M16) and L-Bracket configurations with a 50N striker. The fuses equipped with a 50N striker offer visual fault detection through a bright red-colored striker and can also activate a microswitch assembly for remote monitoring.

High Voltage Fuse

It’s worth noting that all new capacitor fuses equipped with 50N strikers feature a thermal limiter mechanism. This mechanism triggers the striker under overload conditions when the internal temperature of the fuse exceeds specified levels, enhancing safety and reliability.

Hill Tech is pleased to support your component needs for RC transformer protection snubber circuits.

DC Contactor – Power Relay

Durakool manufactures an extensive and diverse product line of high voltage DC contactor and DC relays for switching, as well as medium to high power batteries and chargers serving battery storage, EV chargers, solar and wind energy markets. Durakool also offers custom technical advice so that you can be sure that you are getting optimized components for your project. You will not want to miss out on talking to our team and exploring the innovative capabilities of our design engineers.

DC Contactor DLVC 400

High Power DC Contactor

A new ceramic high voltage DC contactor is available, these contactors contain a sealed ceramic arc chamber that isolates from epoxy sealed DC contactors. This allows for larger DC voltages to be switched. Less battery power is required to power the contactors, because of the twin coil economizers, which results in overall increases in the EV’s driving range, and also makes an additional coil back EMF suppression unnecessary. And in the event of a failure, the main power contacts are mirrored to the position of the mechanically linked auxiliary contact mirrors, and can indicate the power contact’s position as part of a safety monitoring circuit.

Durakool offers high voltage contactor of 900-1500VDC, a high voltage for DC switching contactors, while also providing for more low-power needs, with ones that go as low as 450VDC.

Power Relays

Our high voltage DC contactor relay products are low-cost, compact, and have a long life. Our power relays perform efficiently even in challenging environments. There are over 120 power relays in stock. Of these include the DG3BL PCB Power Relay which contains a magnetic arc blowout that allows the relay to switch 50% higher DC voltage in comparison to relays of its same type. In relation to the PCB, it gets rid of the need to put it through high voltages and currents by using shielded fast-on blades for power terminals.

For any additional assistance, please contact us at sales@hilltech.com or 847-255-4400. You can submit a request for a quote directly by using our automated request system.
