GENERAL: These small but powerful converters provide a source of stabilised low voltage
suitable for running many different items of equipment. Their output is ohmically isolated from the
system chassis and constant current limited. Continuous operation in current limit is allowed
making them suitable for battery charging. Connection to the system is by a 'cigar' plug (12 & 24V
Input) lead or just a flying lead (48V input), and output is by flying lead (5V - 15V units) or 2.5mm
concentric connector (18V - 48V units).
The converters are mainly designed for use with notebook computers that have two wire input.
These converters are current limited above a certain level of demand. The output isolation of the
converter from system ground ensures that earth currents do not flow.
CONNECTION:
Input: For 12V and 24V units, the converter just plugs into a cigar type socket, using the cable
mounted plug provided. Don't leave the converter plugged in when not in use. It will still slowly
discharge the battery. 48V input units must be directly wired to the 48V supply, fused at the battery
source with a 3.15A fuse. The input cable has a YELLOW sleeve fitted close to the case to identify
it. The RED wire connects to battery positive (+) and BLACK wire to battery negative (-).
Output: 15V output or below: Un-terminated cable. 18V output or more, 2.5mm 'barrel'
connectors, centre positive. Red wire or White stripe positive, Black wire negative. The warranty is
not affected if the purchaser fits a different suitably current rated connector.
BATTERY DRAIN: These converters take about 1A at 12V, 0.5A at 24V or 0.25A at 48V for
every 10 watts of load. Input current may reach 10A (12V), 5A (24V), 2.5A (48V).
