Description
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.
Technical data
| Manufacturer | WhisperPower |
| Article number | 50214718 |
| 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. |
