BATTERY PACK VOLTAGE REGULATOR
The tool battery regulator was designed to enable equipment designed for use on a 12V automotive supply to be powered from the range of Bosch Coolpack tool batteries.
This is an ideal solution to provide high current, replaceable power for demanding portable applications (automotive power aids, test equipment, etc.).
The regulator supports both 14.4V and 18V batteries across the range of capacities.
CAPABILITIES
- Automatic 14.4V and 18V operation with shutdown on battery exhaustion to avoid deep discharge
- The durable black anodised aluminium slide connector is one of the key features of the device, which doubles as a heatsink for the regulator electronics.
- PCB mounted power good and fault status LEDs
- 8 way Molex KK series control connector for the enable, power good, current mimic and secondary output signals
- Battery input internally fused at 20A for safety
- Dimensions: H 110mm x W 75mm x D 25mm
- Part number: SEL0092
FEATURES
- Compatible with the full range of Bosch CoolPack batteries
- Durable and functional design
- Cost-effective
- Easy to fit
Versatility / Flexibility
High current power for demanding portable applications
Ease of use
The device has two discrete 13.5V regulated outputs:
PRIMARY REGULATOR
- Output is 13.5V at up to 10A continuous or 15A intermittent
- “Hiccup” current limiting (shutdown/restart) to protect load and supply, adjustable in 1A increments from 1 to 15A using PCB mounted rotary switch
- Thermal shutdown in the event of continuous high duty usage
- Separate active low enable control signal or can be continuously enabled
- Analogue output voltage which mimics the output current to provide an indication of current draw to external equipment
- Output connection via ¼”/6.35mm Faston terminals
SECONDARY REGULATOR
- Output is 13.5V at up to 500mA
- Intended to power control circuits independently of the Primary regulator
- Separate active low enable control signal or can be continuously enabled
- Output connection via the control connector or an optional 2 pin 3.81mm pitch two part Phoenix Contact terminal block
