1-3-70 - Newmar Power Newmar 1-3-70 Heavy-Duty Battery Isolator

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.

The Newmar 1-3-70 Heavy-Duty Battery Isolator is designed for IT and industrial applications requiring efficient power management across multiple battery banks. This unit facilitates simultaneous charging of up to three battery banks from a single alternator source, preventing discharge between batteries. It is suitable for 12- to 36-volt negative ground DC systems, with compatibility extending to systems up to 48 volts DC. The isolator features conservatively rated diodes within a rustproof anodized aluminum heat sink case, ensuring durability in demanding environments. It has a maximum amperage input capacity of 70A and includes stainless steel mounting hardware and protective terminal covers for installation. This product addresses the need for reliable power distribution and battery isolation in heavy-duty settings, provided the alternator has an external excitation lead.
