Introduction

This manual introduces the Kelly isolated DC-DC Converter’s features, specifications and installation. Read the manual carefully and thoroughly before using the converter. If you have any questions, please contact the support center of Kelly Controls, Inc.
Kelly DC-DC Converter covers wide range of DC input voltages of 40V to 200V, and outputs DC 13.5V. It is quite efficient and reliable with a compact size.

Features

  • No arc
  • Can be controlled by key switch directly, no need of external relay
  • By default, key switch is non-isolated, its input connect to B+. Customer can order isolated key switch which is powered by a separate 12V. (For 500W 650W 800WDC/DC)
  • Over temperature protection, shut down at 90°C
  • Over current protection
  • Low voltage protection: stop working at low battery voltage
  • High efficiency with compact size and light case
  • Low standby current: ≤5mA
  • Isolate between input and output
  • The matching connectors and crimp pins will come with each DC/DC converter
  • IP66 protection
