Contactor vs. Relay

Contactors vs. Relays

The part names “contactor” and “relay” are often used interchangeably, and both have the same job of switching and directing electrical power in a circuit. Despite these similarities, they actually are not the same part and carry key differences. When you are trying to figure out contactor vs. relay for your project, which one should you choose? If you’re asked to find specifically a contactor or a relay by a coworker or project manager, what should you be looking for? Let’s figure out what the key uses, similarities and differences are for these devices.

Contactors

Contactors can be defined as an electrically controlled switch or relay. They handle much higher voltages and are used for higher-power applications. They are great for heavy trucks and buses, off-highway vehicles, and EV charging stations. The types of contactors we carry can handle currents of up to 600A and voltages of up to 1500 VDC, but for battery storage solutions, we have contactors that can switch up to 2000A. Types of contactors include high voltage direct current (HVDC), low voltage direct current (LVDC), solid-state contactors (SSC), and definite purpose contactors (DPC).

Relays

While contactors operate with higher voltages, relays handle lower voltages for lower-power applications. Relays are used for industrial automation, HVAC systems, lighting control, renewable energy applications, home appliances, safety and protection, and telecommunications. They can go as low as 24 volts. The types of relays we carry are green energy/HVDC, standard, special function, industrial, latching, signal, PCB mount, and solid state.

Server Farm Efficiency with High-Performance Resistors

In the rapidly advancing field of technology, the backbone of a successful server farm lies not just in cutting-edge software or the latest in server hardware, but in the critical infrastructure that supports it. Among the components that play an essential role in this infrastructure, resistors take center stage, especially during the initial stages of a server farm build-out. At Hill Tech, we specialize in supplying high-quality wire-wound resistors, grid resistors, and load bank resistors that ensure optimal performance and reliability for server farms around the globe.

Why Resistors are Essential for a Server Farm

  1. Load Testing: Before a server farm becomes operational, it’s crucial to simulate the electrical load it will experience. Our resistors offer the perfect solution for load testing, allowing data centers to confirm that their power and cooling systems can handle maximum capacity. This preemptive testing helps detect potential weaknesses in the system infrastructure, ensuring everything is ready for smooth operations from day one.
  2. Thermal Management: During the testing phase, managing heat is as critical as managing the electrical load. Our resistors help stabilize temperatures, preventing possible overheating and ensuring cooling systems are operating effectively. This is vital in maintaining the server farm’s overall health and longevity.
  3. Infrastructure Evaluation: Using our resistors in the evaluation process of your electrical infrastructure can significantly enhance the reliability of your systems. Before servers go live, our solutions help identify any issues that could impact performance, providing peace of mind that all components will function seamlessly together.

Metal Core Board

Metal Core Board Banner

If you work in electronic components, you know that electricity generates heat, and that heat can be potentially dangerous to your projects. Over time, without proper thermal management, excessive heat can cause malfunctions, hot spots, solder joint stress, CTE mismatch, or even shock and vibration. So how do we beat the heat? Well, you could use fans, heat sinks, or heat spreaders, but they can be bulky and a hassle. With the move to miniaturized circuits, they might not be a possibility at all for some devices.

So, what can we turn to instead? Thankfully, some new tech has been introduced that is doing wonders for thermal management. A Metal Core Board (MCB), also referred to as a Metal Core Printed Circuit Board (MCPCB) or a thermal Power Core Board (thermal PCB), is a fantastic solution to thermal issues! But what are these new pieces of technology? How do they work? What projects do they work best with? Let’s explore.

What is a Metal Core Board?

To manage all of this heat away from essential parts of devices, we need to figure out where we need to move it to, and how we get it there. MCBs dissipate heat by taking it from the heat source and moving it through a layer of dielectric. It then moves into a metal base and spreads out through it, dissipating the heat.

See the diagram below that shows how a MCB works! This specific example is how it works for LEDs.

The metal base is usually made of aluminum or copper, and each have their own benefits. Aluminum is able to dissipate and transfer heat very effectively and is more lightweight and less corrosive. Copper has a longer lifespan, a higher current carrying capacity, and is more efficient while allowing for a smaller board size.

We use Direct Thermal Exchange (DTE) Technology, which causes quick heat transfer through a DTE pad instead of through the dielectric. With this technology, any metal base thickness or started dielectric (including FR4 Epoxy or polyimide) will work. It eliminates the need for thermal vias and has a high-power capacity and low thermal impedance. It can achieve conduction of 135W to 300W/mk.

What are Metal Core Boards used for?

MCBs are great for LEDs in general. They are useful for LED lighting boards, backlight units, general lighting, and high-power LEDs. For electric and hybrid cars, they are great for electric motor controls. They are efficient in high power supply devices such as DC/DC converters, switching regulators, and voltage regulators. You can also use them for solar panels, solid-state relays, photovoltaic cells, motor drives, RF and wireless applications, and motion control.
