The Crydom D06D80 is a DC output solid state relay capable of switching 80 amp loads at a maximum voltage of 60Vdc. The D06D80 utilizes a low-impedance MOSFET to switch load power, which reduces power dissipation and enhances life expectancy. The maximum on-state impedance (Rds) for the output of the solid state relay is 0.008 Ohms, which equates to roughly 51W of power dissipation when switching a 80 amp load.
The input of the D06D80 accepts control signals between 3.5Vdc and 32Vdc and incorporates and active current regulating circuit. The input of the solid state relay will pull approximately 10mA @ 3.5Vdc, and not exceed 15mA at 32Vdc. This makes the D06D80 ideally suited for DC applications controlled by a low power PLC or control board.
The epoxy-free design of the D06D80 solid state relay significantly reduces stress placed on internal components. The expansion and contraction of epoxy during normal operation of similar solid state relays in the market can result in the eventual fatigue of components that can result in the premature failure of the relay. The typical MTBF (mean time before failure) of a D06D80 solid state relay is >7 million hours.
A heat sink and thermal compound are typically required to prevent a solid state relay from overheating during normal operation. HBControls offers a range of DC output power controllers, which are solid state relays pre-assembled onto thermally efficient heat sinks and derated to their maximum load current rating in a 40°C ambient temperature.
While the D06D80 is suitable for switching most types of loads, caution must be taken when switching inductive loads to prevent the solid state relay from being damaged by back emf. A simple solution is to place a fast recovery diode directly across the load, with the cathode of the diode connected to the positive terminal of the load, and the anode of the diode connected to the negative terminal of the load.
