The SolidSwitch 104 will switch DC loads of up to 70V/4A and can be controlled by a low power digital signal. The DC load can be resistive, capacitive or inductive (such as the coil of a high-power contactor). It is not reverse polarity protected and not short circuit proof.

• Control an external alternator regulator, such as a Balmar or Mastervolt Alpha pro in a Victron lithium system.
  
• Switch a DC load, such as a light. A low power control circuit, max current drawn will only be 100 μA, can then control a load of up to 4 Amps.
  
• Increase the number of chargers that can be wired to the ATC (allow-to-charge) output of a Victron BMS.
