The Sterling Power CVSR140 is a 140A current-limiting voltage sensitive relay for 12V or 24V systems. It joins your engine and house batteries when there is charge to share, in RVs, vans, trucks and boats, and is built for systems with heavy house loads.
A plain relay can burn out if a big load, like an inverter, pulls hundreds of amps through it. When this relay sees an overload it first cuts the current down to about 6A, then opens safely and reconnects once the load is gone, protecting both the relay and your wiring. It switches on and off automatically by voltage and draws only about 1mA when idle.
Features
- Built-in current limiting with short-circuit protection before engagement
- Automatic 12V/24V selection and automatic voltage on/off
- About 1mA quiescent current and about 0.01V drop
- Adjustable trigger side, custom voltage settings available
- Protects the primary battery from discharge, with a high-voltage trip
- Emergency forced connection of the auxiliary bank
- Time delay and single or twin starter motor disengage connections to protect against starter surge
- Ignition feed input (not always required), with no feed-wire voltage drop
- Waterproof to IP65, SAE J1171 ignition protected, back-EMF spark arrester
- 5-LED display with five alarm functions and safety trips, plus a remote LED connection
