side of the unit. The purpose of the wiring box is to allow the
system installer to supply a 20-30 amp (instead of 15 amp)
shore power input to the 20-1050CULW.
On both the 20-1050CUL and 20-1050CULW the battery
charger in the “Low” setting uses approximately 3.5 amps of
AC power to charge the batteries at the 15 amp rate. The
battery charger, on the “High” setting uses 12 amps of AC
power to supply 55 amps of DC charging.

Hardwiring the AC Input
There are situations where AC loads such as medical equipment
or quartz lights (which usually operate from the inverter power
during vehicle operation) need to operate from shore power
while the charger is operating. In situations such as this, the
system installer can use the model 20-1050CULW with a
hardwire input to set up the system to supply 20 or 30 amp
shore line power to the inverter unit.
When shore power is supplied to the 20-1050CULW, the
inverter is protected in the following ways: 1) The shore power
input passes through the unit's Transfer Relays and into two
circuit breakers; 2) One breaker is 15 amps to protect the AC
output receptacle. The other circuit breaker is 15 amps to
protect the battery charger AC input circuit.
Certified to Federal
Specification KKK-A-1822D
Vanner’s model 20-1050CUL/CULW and model
20-1000TUL.2 AC Power Systems have been
certified by Underwriter’s Laboratories (UL) to
meet the requirements of the Federal specification KKK-A-1822D. These
units are UL and C-UL Listed (UL Listed to Canadian National Standards)
to meet Power Inverter Emergency/Land Vehicle requirements.
Vanner Model 20-1000TUL.2
The Vanner Model 20-1000TUL power inverter system has
been the standard of the ambulance industry for many years.
Redesigned in 1996, the 20-1000TUL.2 contains the same DC
to AC inverter component as the 20-1050CUL/CULW and has
an automatic heavy-duty AC transfer switch without the battery
charger.
The 20-1000TUL.2 inverter works in conjunction with Vanner's
30-10 and 30-10GFI Battery Charger/Conditioners, has front
panel status LED indicators, and remote monitor/control
capabilities when used with the optional IFM1 Interface
Module.
