Vehicle Mount Power Supply Specifications

Aluminum enclosure. LPP105 is also epoxy-filled.

Constructed to a high standard to tolerate adverse environmental conditions.

Durable for vehicular applications.

Supports battery supply variations.

High and low voltage windows for shutoff, to protect the terminal from overvoltage damage.

Remote low power switch on all units. Can also be wired for direct connection.

Vehicle Mount Power Supplies - Common Specifications and Characteristics

Efficiency: >80%.

Switching Frequency: 50 KHz.

All units are CE Marked.

Conformance to: EMC EN 55022, EN50081-1, EN50082-1, FCC Class B, UL 1950.

Input Protection: Reverse polarity, with additional protection: (See below)

Output Protection: (See below)

Mounting: All mounting holes 5 mm (.2") diameter.

Weight: LPP101(12VDC) & LPP102(24VDC): .5 Kg / 1.1 lbs.; LPP103(36VDC) & LPP104(48VDC): .35 Kg / .8 lbs; LPP105(72VDC): 1.6Kg / 3.5 lbs.

Remote Switch: All units

Switch connection: To use remote switch, connect the remote input to one side of switch, and the + input to the other side. If switch is not required, the switch input must be connected to + input.

Nominal input voltage must be applied to remote switch line to turn unit on.
