Description

The VTC1505 Series of voltage converters provides 12, 24 or 48 Volts DC at
25 to 100 Amps of continuous power from a 110, 250, 300 or 360 Volt DC
source.

Analytic Systems' Voltage Converters use Switchmode technology with
powerful IGBT switching transistors for reliability and efciency with
minimum size. Circuit innovations reduce output ripple to levels previously
available only from bulky and inefcient linear power supplies. Reliability
features include an input fuse, thermal shutdown, current limiting and output
short circuit protection with automatic recovery. An Output Over voltage
Crowbar circuit protects any powered devices from excessive voltage in the
event of a failure of the unit.

The newly updated single-board VTC1503 is ultra-quiet and features the
latest generation of current mode PWM control. Extra features include
audible and visual indicators for over temperature and output on.

Applications

• Marine & other rugged environments

• Automotive / RV

• Electric Utilities and Substations

• Base Station Power (Radio & Telecommunications)

• OEM Applications

• Field Work / Construction Sites

• Solar Power Systems

• Emergency Power Backup (UPS)

• Security Systems

• Power any 12, 24 or 48 Volt Electronic Equipment
