Newmar 1-3-70 Heavy-Duty Battery Isolator

This robust battery isolator enables the charging of multiple batteries simultaneously from one or two alternators while preventing the unwanted discharge or 'dumping' of power from one battery to another. Each battery is charged according to its requirements without the risk of overcharging, and it operates efficiently within 12- to 36-volt negative ground DC systems.

Key Features:

• Conservatively rated diodes with a rustproof anodized aluminum heat sink case.
• Designed for heavy-duty applications.
• Compatible with systems up to 48 volts DC and negative ground configurations.
• Durable, rust-proof anodized aluminum casing.
• Includes stainless steel mounting hardware.
• Comes with protective terminal covers.

Specifications:

• Alternator Sources: 1
• Battery Bank: 3
• Max. Amperage Input Capacity: 70
• Stud Terminal Size: 6mm
• Dimensions (L x W x H): 3.25 x 4.5 x 3.1 inches
• Weight: 2 lbs.
• Operating Temperature: -40 to +80 degrees C
• Duty Cycle: Continuous rating to 50 degrees C; derates linearly to 70% at 80 degrees C.
• Temp. Rise: 5 degrees C at full rated current (mount vertically for optimal cooling).
• Voltage Drop: 0.7V @ 50% load, 0.9V @ full load.

*Note: This battery isolator is not suitable for self-exciting alternators. The alternator must have an external excitation lead. Consult with your alternator's manufacturer if uncertain about your configuration.
