About this item

  • ★Input Voltage/Output Voltage: 3-32VDC/5-220VDC; Current & Frequency: 25A
  • 【Control Method】: DC to DC
  • ★Ideal for automatic process control application, a must component for temperature controller and other machinery control system.
  • ★Used for various household/industrial automation process control applications, such as heating & cooling controler, temperature controller, numerical-controlled machinery, remote-control system, etc,and it is a good substitute.
  • 【Note】: Cannot be used for more than 25A for a long time. If that actual use current exceeds 15A, It is necessary to separately configure the heat sink, If you want to reach 60A, you need to add a large heat sink and fan.

I love these Solid Stare Relays. There so flexible with the input power. What I didn't care for is the terminal screw broke when tighten it.

The relay works fine for my use, which is 12V and 10 watts, but I was disappointed with the connectors. My solid strand wire came lose unless I tightened the connector while the wire was centered. There should be a better contact point under the connector hood to hold down the wire. The plastic guard to go over top is nice.

The first pair of these performed well, 0.25V drop at 11 amps current.Alas, the 1st of a second pair was just over 1V drop at 11 amps. So it's obvious that random power transistors are being installed in these. So I can no longer recommend these.In one 40 amp, 60V Fotek labled DC to DC SSR I found a 15 amp rated bipolar power transistor (400V), with no heat sink attachment to the metal base plate. No wonder two melted and failed at 10.5 amps.It would be nice if there some reliable SSRs being sold out of China. But it appears not.
