DC Panel Mount Solid State Relay

DC-DC RELAYS mosfet based

SatronixDC output solid state relays are being used more and more widely. One of the major reasons for the use of solid state relays for switching dc is the fact that as there are no moving parts there is no contact arcing or wear out mechanism. However, there are some precautions which have to be taken when using solid state relays with inductive dc loads

All parameters at 25°C unless otherwise specified In-built freewheeling diode across the power device.

Note: Inductive loads should be diode suppressed. All loads are inductive even ones that are not so labeled. When turned off an inductive load will produce harmful transient voltages. The more perfect the switch the larger the transient voltages. The IGBT output is so nearly an ideal switch that the transient voltages produced by seemingly 'non-inductive 'loads can cause damage if not suppressed. Diodes should be fast recovery type with PIV rated greater than supply voltage.
