24V DC INPUT (19-36V) - DDH 150 SERIES

Make enquiry Product Matrix

Features

  • The DDH 150 features a switch selectable ‘low’ output voltage for working as a DC power supply and a ‘high’ output voltage which allows the user to float charge a lead acid battery from a battery.
  • Galvanic Isolation between input and output (500V max.)
  • Ambient Operating Temperature : 0-450C
  • Efficiency: typically 80% at full load
  • Substantial Input Filter
  • Thermal protection by self-resetting trip. This operates when the heatsink reaches 900C and resets when the temperature drops to 700C
  • Indication for ‘output on’
  • Low current on/off control input (<3mA sink to negative to turn on)
  • Stabilised output voltage
  • 2 :1 Input voltage range
  • Convection cooled
  • Weight : 1.2kg
  • Dimensions : 180mm x 158mm x 65mm
  • Input & Output Connections: Screw Terminals that accept up to 4mm2 cable
  • Protection for :- reverse polarity on input and output

input under voltage (shutdown, auto re-start)

output over voltage (shutdown, auto re-start)

short circuit output (electronic current limit)


The Technology

The DDH150 range of DC-DC Converters use high frequency switched mode technology for high efficiency, small size and light weight.

‘Current Mode’ circuitry ensures reliable operation even for the arduous task of battery charging. Mosfet switching devices produce superb performance and only the highest quality components are used throughout.

Isolation

Galvanic Isolation between input and output cures difficult ground loop problems, allowing optimum wiring in complex systems. This can avoid noisy power lines degrading signal lines.
