SERIES "ST" [24 V to 12 V DC-DC Converters for Communications Equipment]
SEC America, LLC - engineering and marketing company specializing in power conversion equipment. [ P.O. Box 2266 South Burlington, Vermont 05407 - Phone:(802) 865-8388 ]

 
24 V to 12 V DC-DC Converters for Communications Equipment - Series "ST"
 

Series "ST"
24 V to 12 V DC-DC Converters for Communications Equipment
 
ST Series converters interface between high voltage DC battery sources and communications equipment that is designed to operate from 12 VDC electrical systems. These converters furnish harmonic and noise free pure DC power. When energizing even the most sensitive communication apparatus, the quality of the converter output ensures that optimum performance will result from the equipment.

Although primarily designed for 24 VDC to 12 VDC down conversion, these models may be used for input voltages ranging from 18 VDC to 30 VDC. All ST Models must be used on negatively grounded vehicles only.
APPLICATIONS IN:
  • Tractor Trailers
  • Buses
  • Loaders
  • Boats
  • Logging Vehicles
 
FEATURES:
  • Low Noise Output
  • Overload Protection
  • Overvoltage Protection
  • Wide Input Voltage Range
  • Rugged Aluminum Chassis
  • Easy Installation
  • 1 year Warranty
Specifications  
Model ST 340
 
Input Voltage:
 
18 VDC to 30 VDC
 
Output Voltage:
 
13.8 VDC ± 0.2 VDC
