VTC1015 Series DC/DC Converter
NSN#
VTC1015
BENEFITS
- Ultra-Quiet
- Power sensitive electronics without interference
- Rugged & Reliable
- Ensure years of safe and trouble free operation
The model VTC1015 Voltage Converter supplies either 12V, 24V, or 48 VDC from
a 24V, 48V, or 72VDC power source.
All new Current Mode switching design offers increased power and reliability
in a compact package. Extra input and output filtering reduce EMI to extremely
low levels. Reliability features include an input fuse, thermal shutdown,
current limiting, reverse battery hookup protection and output short circuit
shutdown with automatic recovery.
The output voltage is easily adjusted 1.0 volts above or below the standard
output voltage. Devices connected to the converter are protected by an output
overvoltage crowbar circuit.
Optional features include a Remote Control, a 19? Rack Mount version, and/or
a Digital Volt Ammeter to allow monitoring of output current and output voltage.
