WhisperPower Remote Battery Switch 48 V / 350 A

The DC Modular Remote Battery Switch 48 V / 350 A is a smart high current magnetic latching contactor, that can handle continuous DC currents of up to 350 Amps. The Remote Battery Switch 48 V / 350 A can easily be installed in an engine room or battery compartment while being controlled from a more convenient location by a small panel mounted switch. But the Switch can for instance also be controlled by a battery monitor or Lithium battery, as a discharge/overcharge protection.

• Smart terminal design allows dual mirrored cable lug connections
• Stainless steel studs, washers and nuts for optimal corrosion resistance
• Local Open and Close buttons on top, to manually override the switch state
• Robust transparent covers with breakouts to allow wire access from any direction

Technical specification

PARAMETER
Rated voltage	60 VDC
Nominal current @ 25 C	500 A (see precaution #2)
Cranking current (1min.)	1000 A
Nominal make / break current	350 A (35 - 60 VDC)
Peak make / break current	1200 A (35 - 60 VDC) (Install proper pre-charge circuit to keep peak make current significantly below this value)

CONTROL CIRCUIT (ELECTRICAL)
Coil / supply voltage (+ VDC)	34 - 68 VDC
Coil / supply current (idle state (1)	< 100 qA
Coil / supply current (state change (1)	< 1.5 A
(1) =	Due to the magnetic latch construction, the DCM-RBS draws virtually no current in the ON or OFF state. A current draw only exists shortly (500 ms max.) when changing the state of the contact.

GENERAL
Remote control	By control wires
Local control (2)	Top side buttons (On/Standby, Close contact, Open contact)
Length x width x height	150 x 50 x 94 mm (5.9" x 2" x 3.7" inch)
Weight	0.8 kg (1.8 lb.)
Indicators	Top side LEDs for Contact open, Contact closed, Error and Setup
Mechanical life	100000 cycles
Electrical life	10000 cycles
Operating temperature range	- 20 .. + 60 °C
Connection stud size / DCM grid size	M10 / 1 x 3
Protection class	IP65
Standards	CE certified (EMC Directive 2014/30/EU, Low voltage Directive 2014/35/EU, RoHS Directive 2011/65/EU and Ignition protection standard ISO 8846)
(2) =	Using the top side buttons, one can manually override the switch state as commanded through the control wires. A dedicated 'On / Stand' button also allows the user to put the DCM-RBS in a standby mode with open contact. In this mode any command from the control wires and/or manual override buttons are ignored.
