Description
NGVB-HC: Negative Ground Voltage Booster – High Current
Voltage Booster for Negative Ground Systems (for positive ground systems please see PGPI-HC)
The NGVB-HC Voltage Booster will operate 12-volt negative ground accessories from 6, 8 or 12 volt negative ground electrical systems.
Because of its efficient design, it’s current draw is negligible when no load is applied. Unlike conventional boosters which use a transformer, it can be used for memory maintenance or alarm systems in the standby mode for long periods of time without discharging the battery. Quiescent current draw is about 10 milli-amps.
The inverter is a cube 1-3/4 inches on each side. Due to its very small size, it can often be mounted directly to the accessory it is intended to operate.
The NGVB-HC Voltage Booster is designed to operate with any input voltage from +4 volts to +11 volts. It is protected against reverse polarity, overload and short circuits. Note: For continued protection, never replace the input fuse with anything greater than a 10-amp fast acting (3AG type) fuse!
The maximum output power is a function of input voltage. The greater the input voltage, the greater the output voltage will be. When used in a 6-volt system (operating at 7.2-volts), it can continuously supply more than 3.5 amps with the engine off, and about 5 amps with the engine running at a fast idle. You should know the average and peak power requirements that your accessory will require. Brief excursions above the maximum output rating will not damage the voltage booster but may result in reduced output voltage while the overcurrent condition exists.
Installation of the NGVB-HC: Using the mounting screw and lock washer provided (remove the black wire connected to the top of the case), fasten the unit directly to a metal (grounded) surface behind the dash or in any convenient location. If it i not possible to directly attach the voltage booster to a metal, grounded surface, the black wire provided may be run from the case screw to vehicle ground. Note: The voltage booster must have a good (chassis) ground to operate properly. Connect the input wire (red wire with the fuse) to the ACC terminal of the ignition switch or the power source for the accessory being connected (example: The radio terminal of the fuse block). Connect the output wire (red wire without a fuse) to the power input of the accessory you intend to operate
For troubleshooting tips or further information please reference the instruction manual.
This voltage booster is designed to power car radios and other accessories. This unit is not recommended for: power actuated door locks, trunk release solenoids, air conditioner clutches, fans, blowers, power windows or other electromechanical devices. This voltage booster will not work in positive ground electrical systems.
