Frequently asked questions

What is a solid-state relay?


A solid state relay is essentially an electronic switch or relay, but without any moving parts. When an input signal is provided, normally in the form of an AC or DC voltage, the output circuit closes and allows current to flow through a load, such as a heating element or motor.

Solid state relays have no moving parts, which differentiates them from other forms of power-switching devices, such as electromechanical relays or contactors. As a result, there is no acoustical noise when a panel mount solid state relay switches power to / from a load. More importantly, the lack of moving parts is the primary reason that the life expectancy of a solid state relay is significantly longer than comparable mechanical devices. The typical MTBF (mean time between failures) for a solid state relay is >700 years when operated within their specifications.

Solid state relays can be used almost anywhere power needs to be switched to / from an electircal load. The most commonly used relays in the market are either a 25 amp solid state relay or a 50 amp solid state relay, since they cover a vast majority of the markets' power switching requirements. However, a wide variety of models with ratings up-to 150 amps AC or DC are available for higher power applications.




Do I need a heat sink for a solid state relay?


Yes, in most cases. Once the load current goes above 5 to 7 amps, some form of heat sink is required to prevent a solid state relay from overheating. This is due to the fact that solid state relays dissipate power in the form of heat at a rate of about 1 watt per ampere of load current.

The simplest solution to avoiding thermal calculations and heat sink assembly is to use an HBControls power controller. Power controllers are panel mount solid-state relays pre-assembled onto thermally efficient heat sinks, with the assembly already fully derated to a maximum load current in a 40°C ambient temperature. The heat sink used is either DIN mount or panel mount.

Our TechTip article on how heat sink selection impacts the load current rating of a solid state relay provides more detailed information. Additional information on solid state relays and heat sinks can be found in the technical section of our website.




What's the difference between a CWD, HD and D series DC input solid state relay?


In forms of function, all three series are identical. The primary difference is in their actual ratings. The Crydom D series, also referred to as the Series1 solid state relays, have load current ratings that can go as high as 125 amps with a maximum line voltage (output voltage) rating of 280Vac. The HD series relays also have ratings up-to 125 amps but with a higher line voltage ratings. The HD48 series, for example, has a line voltage rating of 48-530Vac, while the HD60 series as a line voltage rating up-to 660Vac.

As previously mentioned, the CW48 series panel mount solid state relays perform the same function as the Series1 and HD series relays. However, they have a few additional features and benefits, including an integral IP20 “touch-safe” cover and standard LED input-status indicator.




What is the input voltage and current requirement for turning on / off a DC input solid state relay


The Series1 (D24xx) solid-state relays have an input voltage range of 3-32Vdc, while the HD48, HD60 and CWD48 series solid-state relays have an input voltage range of 4-32Vdc. The increase in the minimum turn-on voltage for the 480Vac and 660Vac solid state relays is due to the fact that two optical isolators are used in their trigger circuit instead of just the one optocoupler required for a 240Vac solid state relay. The additional voltage drop across the input of the extra coupler forces the minimum turn-on voltage to 4Vdc.

The input circuit of all three solid state relay families is current regulated, meaning that the amount of current “pulled” by the input circuit is relatively flat over the full specified voltage range. At their minimum rated input voltage, the Series1 and HD series will pull approximately 7mA of input current, while the CWD48 series solid state relays will pull approximately 10mA. At their maximum 32Vdc input voltage rating, the Series1 and HD series relays will pull a maximum of 12mA, while the CWD48 series will pull a maximum of 15mA.




How does the output circuit of a panel mount solid state relay switch power to/from an AC load?


HBControls primarily uses Crydom solid state relays, which utilize discrete SCRs configured in inverse-parallel to switch AC current. This design is significantly more reliable than a solid-state relay using TO-220 packaged triacs commonly used by manufacturers importing low-cost solid state relays, primarily because discrete SCRs generate less power and dissipate heat more efficiently.




What’s the difference between zero-crossing and instantaneous (random turn-on) solid-state relays?


“Zero-crossing” solid state relays will not conduct load current when an input signal is applied until the sine wave is near its zero-crossing point. This minimizes inrush / surge currents through the load since the voltage across the load will be close to 0Vac whenever the solid-state relay turns on. Instantaneous (also called “random turn-on”) solid state relays will begin conducting load current within 100µS of receiving an input signal, regardless of the sine wave voltage.

Zero-crossing relays are the most common solid-state relays in the market and are suitable for most types of AC loads. Instantaneous solid state relays are commonly used in phase-angle control applications, or in applications where there is a significant phase shift between the output voltage and current due to the load being highly inductive.

Most solid state relays are available with either a zero-crossing or instantaneous output. For example, the D2425 is a 25 amp solid state relay with a DC input and zero-crossing output, suitable for most types of loads. However, if the load is inductive, or if it's a phase-control application, then a D2425-10 25 amp solid state relay with an instantaneous turn-on output could be a more suitable alternative.
