Voltage Sensor Relays

Open and close circuits based on the amount of voltage flowing between them with a voltage sensor relay (AKA VSR). Commonly used to control the charging of large vehicle batteries, these current sensing relays guard against over discharging in a dual battery system. Voltage sensitive relays may vary by sense configuration (dual sense or single sense), number of contacts, contact rating, pick up range, drop out range and other considerations. For more electrical relay items, see our time delay relays, relay sockets, and solid state relays.
