Description
The Modular Electric System belongs to a new generation of in-line devices
using modern, primary-switched circuitry. The device supplies filtered, stabi-
lised 12 Volt DC over the full range of its output power. The Modular Electric
System incorporates a method of switching automatically between mains and
vehicle battery operation. Mains operation has the highest priority, in order to
minimise use of the vehicle battery. Voltage variations are compensated for in
mains operation, so that the Modular Electric System maintains full perform-
ance even when the mains drops below 230 Volts. All 12 Volt outputs are
secured with push-in fuses. The 230 Volt input is secured with circuit breakers.
This generation of in-line devices is marked by high efficiency and only very
low heat generation. The low weight allows it to be mounted in almost any
position (preferably suspended).
Mains operation
If the Modular Electric System is connected to the 230 Volt mains, then it
automatically switches to mains operation. In mains operation, both the 230
Volt outputs and the 12 Volt outputs are supplied with power. The 12 Volt
outputs are supplied with filtered, stabilised 12 Volt DC. If the mains supply
fails, the Modular Electric System automatically switches to providing power
from the vehicle battery. It is necessary for the connection to the vehicle bat-
tery to have been made.
Driving operation (vehicle battery operation)
If the mains supply is interrupted, the device switches automatically to vehicle
battery operation. The 12 Volt input is now connected. The 12 Volt outputs are
now supplied from the 12 Volt input coming from the vehicle battery.
