Automatic Charge Relays

SI-Series Automatic Charge Relay
An automatic charge relay supporting alternators up to 120 amps. Protects sensitive electronics by temporary isolation of house loads from engine circuit during engine cranking. 12/24 volt auto raniging voltage input with hermetically sealed vaporproof contacts. Waterproof rated IP67 - temporary immersion for 30 minutes. Sense either battery voltage and supports a remote LED to indicate relay state.

Mini ACR
The Mini automatic charge relay is ideal for outboard powered boats and many smaller inboard boats. In a 12 volt dual battery installation it automatically connects the batteries together when the engine is running, and disconnects them when the engine stops. It can be used to make sure that an engine start battery cannot be discharged inadvertently by entertainment systems or refrigeration. For use with alternators up to 65 amps, it senses battery voltage on both terminals and has a LED status indicator.

Charge Relay Auto 500A

Features:

•Manual control switch provides an added level of safety allowing control with or without power, and offering LOCK OFF capability for servicing
•Includes ML-Series Remote Control Contura Switch PN 2146
  • Automatically manages the charging of two large battery banks
  • Allows paralleling of battery banks for emergency starting
  • 500 Ampere continuous rating to support high-output alternators
  • Magnetic Latch (ML)—ACR draws very low current (<40mA to monitor terminal voltage) in the "ON" or "OFF" states, and draws moderate current for very short time when changing state
  • Dual sensing—senses charge on both battery banks
  • Start Isolation (SI)—can be configured for temporary isolation of House loads from Engine circuit during engine cranking to protect sensitive electronics
  • Engine Isolation (EI)—can be configured for isolation of two engines while both are running to protect engine electronics and maximize alternator output
  • Senses charging on two battery banks
  • LED output to remotely indicate when batteries are combined, isolated, in voltage lockout, or in Start or Engine isolation
