55 Amp-High Setting/15 Amp-LowSetting
•AutomaticACTransfer Switch
•UL Certified to Federal Specification KKK-A-1822D
•Underwriters Laboratories Listed (UL and C-UL Listed)

•Ground Fault (GFCI) Protected ACOutput
The Vanner 20-1050CUL/CULWACPower Systemcombines apowerful DCto ACpower inverter with an automaticbatterycharger/conditioner and a 30 amp ACtransfer switch. Whenconnected to shore power (ACutilitypower) the vehicle’sbatteryis charged, then automaticallymaintained in fullcharge condition. The shore power is automaticallyconnectedto the system’s ACoutput receptacle to supplypower to the ACloads. When shore power is disconnected (vehicle underway)the automatictransfer switch connects the ACoutput receptacle
to the power inverter, which obtains power fromthe 12 voltbattery.
The 20-1050CUL/CULWsystemcontainsa front panel LEDindicator status paneland interface connectorfor the remotemonitor/control units.
A set of remote options allowflexibilityin configuring theinverter systemfor specificneeds. The optional IFM1 InterfaceModule, enables the two remote status panels, systemon/off switch, and the Inverter Lockout Interlock to be connected tothe 20-1050CUL/CULWsystem.
12 Volt Power Inverter The power inverter is a highlyreliable electronicpowerconversion unit that utilizes MOSFET power semiconductors anda microprocessor controller. It converts 12 volt DCbatterypowerinto 1050 watts of modified sine wave 120 volt ACpower. ThisACoutput power is preciselyregulated at 120 Volts ±5% and60Hz ± 0.1Hz.
Battery Charger/Conditioner
When the systemis connected to shore/utilitypower the batterycharger/conditioner will automaticallycharge the battery, thenkeep it fullycharged. The system's microprocessor controls thecharging sequence, starting with the Bulk charge (55 amps onHigh setting, 15 amps on Lowsetting) mode. When the batteryis fullycharged, it switches to the ready/maintenance mode tokeep the battery“topped up”. The unit is designed to chargeeither lead acid flooded (wet) or gel type batteries.
Automatic AC Transfer Switch
The 20-1050CUL systemis provided with a 2.75 ft. ACpower
line cord. When connected to shore/utilitypower, the internaltransfer switch routes the incoming 120 volt ACpower to the ACoutput receptacle and to the input of the batterycharger/conditioner. In this mode, loads connected to the ACoutputreceptacle are supplied with shore/utilitypower and the batterycharger/conditioner will automaticallycharge and maintainthe battery. When the shore/utilitypower is disconnected, the120 VACoutput receptacle is switched fromshore/utilitypowerto the power inverter. If the inverter switch is On, the powerinverter immediately(within 30 ms) supplies ACpower to the
ACoutput receptacle.
Model 20-1050CULW
The difference between a hardwire unit (20-1050CULW) and anon-hardwire unit (20-1050CUL) is in the 120 VACinput wiringto the AutomaticACTransfer Switch. The actual function of the Transfer Relaysystemin the 20-1050CULWis identical to the20-1050CUL; however, on the 20-1050CULWsystem, the ACinput is hardwired through a wiring boxlocated at the back

Vanner Model 20-1000TUL.2AC Power Inverter System
Key Features
•1,050 Watt Power Inverter

side of the unit. The purpose of the wiring boxis to allowthesysteminstaller to supplya 20-30 amp (instead of 15 amp)shore power input to the 20-1050CULW.
On both the 20-1050CUL and 20-1050CULWthe batterycharger in the “Low” setting uses approximately3.5 amps of ACpower to charge the batteries at the 15 amp rate. The
batterycharger, on the “High” setting uses 12 amps of ACpower to supply55 amps of DCcharging.

Hardwiring the AC Input
There are situations where ACloads such as medical equipmentor quartz lights (which usuallyoperate fromthe inverter powerduring vehicle operation) need to operate fromshore powerwhile the charger is operating. In situations such as this, the
systeminstaller can use the model 20-1050CULWwith ahardwire input to set up the systemto supply20 or 30 ampshore line power to the inverter unit.
When shore power is supplied to the 20-1050CULW, theinverter is protected in the following ways: 1) The shore powerinput passes through the unit's Transfer Relays and into twocircuit breakers; 2) One breaker is 15 amps to protect the ACoutput receptacle. The other circuit breaker is 15 amps toprotect the batterycharger ACinput circuit.
Certified to FederalSpecification KKK-A-1822D
Vanner’s model 20-1050CUL/CULWand model
20-1000TUL.2 ACPower Systems have been
certified byUnderwriter’s Laboratories (UL) to
meet therequirements of theFederal specification KKK-A-1822D. These
unitsareUL and C-UL Listed (UL Listed to Canadian National Standards)
to meet Power Inverter Emergency/Land Vehiclerequirements.
Vanner Model 20-1000TUL.2
The Vanner Model 20-1000TUL power inverter systemhasbeen the standard of the ambulance industryfor manyyears.Redesigned in 1996, the 20-1000TUL.2 contains the same DC
to ACinverter component as the 20-1050CUL/CULWand hasan automaticheavy-dutyACtransfer switch without the batterycharger.
The 20-1000TUL.2 inverter works in conjunction with Vanner's30-10 and 30-10GFI BatteryCharger/Conditioners, has frontpanel status LEDindicators, and remote monitor/controlcapabilities when used with the optional IFM1 InterfaceModule.

Remote SystemOn/Off Switch
This switch allows the ACPower Systemto be remote controlledand normallywould be installed near the Remote PowerInverter Panel. This On/Off switch controls the power inverteronly. In the
20-1050CUL/CULWsystemthe batterycharger/conditioner will always beOn if shore/utilitypower inpresent. The remote switchis provided with an eightfoot (8') cable that connectsto the IFM1 InterfaceModule.
Remote Power Inverter Panel
This remote panel containsa green INVERTER LEDthat shows when theinverter is in Standby(flashing) or On (steady). Ared FAULT LEDshows aproblemsuch as Over Temperature, Output
Overload or LowBattery. The panel has a sealed front overlayand can be mounted on a flat surface with four screws. A 12"wiring pigtail is provided to allowwiring to the IFM1 InterfaceModule.
Remote Charger Indicator Panel
This remote panel contains a green CHARGINGLEDto showwhen ACshore/utilitypower is present, charging and main-taining the battery. A red FAULT LEDshows the charger is
Off due to a problemsuchas Over Temperature orOverload. The panel has asealed front overlayandcan be mounted on a flatsurface with four screws.A 12" wiring pigtail isprovided to permit wiringto the IFM1 InterfaceModule.
The 20-1050CUL/CULWand 20-1000TUL.2 ACPower InverterSystems support a varietyof options designed to maximize thevehicle’s electrical power capabilities. Systemoptions include aremote shore power/charging status panel, a remote inverterstatus panel, a remote systemon/off switch, and the IFM1
interface module.
Interface Module
This Interface Module (Model IFM1) enables various remoteoptions to be connected to the 20-1050CUL/CULW, or
20-1000TUL.2 Power System. The IFM1 is supplied with a twofoot (2') data cable to connect it to the inverter system.Electrical terminals on the IFM1 permit wiring to the tworemote status panels, remote on/off rocker switch, and to themodule disconnect switch for the inverter lockout control. TheIFM1 can be mounted convenientlynear the 20-1050CUL/CULW, or 20-1000TUL.2 unit.
In order to meet the Federal KKK-A-1822Dambulancespecification requirements it is necessaryto add an inverterlockout control. This control is provided bythe IFM1 InterfaceModule. The Inverter Lockout Control terminal on the IFM1 iswired to the emergencyvehicle's module disconnect switch loadside. This control interlock ensures that when the ModuleDisconnect Switch is off, the 20-1050CUL/CULWor20-1000TUL.2 cannot switch into the inverter mode, whichcould discharge the vehicle’s battery.
