Operation
Normal Operation:
VC-30 will provide up to 30 amps continuous output and maintain 13.5 volts output voltage across the full
range of DC input voltage.
VE-30 will maintain the voltages between two batteries wired in series. It will supply up to 30 amps of output
to the 12V battery from the 24V battery to maintain equalization.
No output condition: DC input voltage must be above 18 volts for the unit to “turn ON” and must remain
above 14 volts during operation.
Overload Condition: An overload condition exists when the 12 volt load exceeds the output rating of 30
amps. The symptoms that indicate an overload condition exists are output voltage below 18VDC combined
with 30 amps output current. The overload condition will not damage this equipment. During the overload,
internal protection circuits reduce output voltage as needed to limit the output current to 30 amps.
Ignition VC-30:This equipment will turn off if the ignition line is below 1.5 volts and the load current drops
below 0.5 amps.
Ignition VC-30-NLC/VE-30:The converter will turn off if the ignition line is below 1.5 volts, regardless of the
load current.

Installation Recommendations
Caution: This equipment employs components that tend to produce arcs and sparks. To prevent fire or
explosion, do not install incompartments containing batteries orflammable materials. Safetygoggles should
always be worn when working near batteries
Terminal Connections: This equipment is supplied with a APTIV Metri-Pack 280 Series, 5-position
connector. The mating connector is APTIV P/N: 12186400, appropriate wire seals sized to the wire outside
diameter arerequired andnotincluded. The wire should extenda minimum of two inchesfrom theconnector
in the same plane to maximize the weather resistance of the connector.
The terminations are as follows:
A: +12V Output
B: Ground
C: +24V Input
D: Over Temperature (output isa switch closure to groundcapable of sinking100 ma, MAX,useable
for a dash light, etc.)
E: Ignition
Fusing: A fault protectiondevice mustbe installed between this equipment and thepower source(battery).A
fault protection device would be any fuseor circuit breaker properly rated for themaximum DCinput current.
This advisory is in accordance with SAE, NEC and UL, for mobile power applications.
Minimum Wire and Fuse Sizes: Connect thisequipment to the 24vdc source using10AWG cableprotected
by a maximum 40-amp fuse or circuit breaker. Using the same size cable for all circuits is recommended.
Install adequate fuse protection if smaller cables are used.
Wire Temperature rating: Recommended wire ratings should be 125ºC, minimum of 105°C.
Mounting Location: This equipment may be mounted in any orientation, however for optimum cooling,
mount the converter with fins vertical.
Environmental Protection: Protect the unit from direct exposure tomoisturesuchashigh-pressurewashing,
rain, etc.

Validate converter output by checking for 13.5+/- 0.5V at 12V distribution busbar
If there is no converter output, check the following:
>10VDC on converter pin E
>20V on converter pin C
Ground continuity on converter pin B
