SSR 40DD DC Control DC Solid State Relay Introduction:

  • The SSR 40DD is a DC control DC 40amp SPST(Single Pole Single Throw) normally open solid state relay, the control voltage is 3-32VDC, load voltage is 5-220VDC.
  • Therefore, we can use a 12VDC or 24VDC switching mode power supply(SMPS) to turn on or off a big DC load. This charateristic makes this solid state relay a safe switch.
  • This DC DC SSR can be used in an off-grid solar power system to cut off the power from the battery bank. Please note that this solid state relay maximum output current is only 4oA.
  • The Solid-state relays generate much heat during operation. As the load current exceeds 10 amperes, so we shall use a W-70 radiator. Also, please place thermal grease between the solid-state relay baseplate and the heat sink. For the SSR currents above 60A, please consider to use a fan for additional cooling.
