Crydom DC SSR (Solid State Relay)

This Crydom D1D40 SSR is rated for up to 100VDC and 40 amps. It is intended to be used on MPPT regulators that have 12V (3-32V range) AUX relays for diversion of surplus power once the batteries are full. We suggest that you do not drive it at more than 20 amps without fan cooling, so ensure you fit the correct resistor size to limit maximum current draw.

We also have limited stocks of:

• D2D12 (for up to 200VDC and 6.0 amps continuous without fan cooling)
• D4D07 (for up to 400VDC and 3.5 amps continuous without fan cooling)
• D4D12 (for up to 400VDC and 6.0 amps continuous without fan cooling)
• D5D07 (for up to 500VDC and 3.5 amps continuous without fan cooling)
• D5D10 (for up to 500VDC and 5.0 amps continuous without fan cooling)

Higher voltage SSR's can be used for input side switching for 150-500V MPPT regulators.

For SSR applications above 100 VDC and 120/240 VAC phase angle SSR applications Hugh Piggott (via a consultation) can assist/advise you.

We recommend that you read our PS MPPT Diversion Loads Guide.
