TSM DC-DC Converters

In stock

Thunderstruck Motors Isolated DC-DC converters have 13.8V output with a max of 50 amps (burst at 12V).  8"x5.5" Footprint. 3 lbs. 

The ipDCIS series isolated DC-DC converter utilizes advanced high frequency power conversion technology and is designed to convert high voltage battery power for a 12V vehicle accessory system including battery charging, lights, electronics, etc.

This DC-DC converter is electrically isolated from input to output to ensure safe use, operates at a high efficiency, and has a stabilized output voltage capable of charging 12v batteries and safely operating electronic equipment. Multiple DC-DC converters can be used in parallel  to increase output current. 


  • Damage to the DC-DC will occur if you swap input and output wires, or if you apply reverse polarity to the connectors.
  • Do not open the DC-DC Case - there is a risk of electric shock, and your warranty may be void. 
  • Fuses are recommended at battery connections based on wire size/capacity - not shown in the following drawings.
  • We recommend an external battery maintainer for the 12v system if it is unused for a month or more.

Output Voltage Volts 13.8 (no load)
Output Current Amps 50
Maximum Efficiency % ≥88%
Environmental Enclosure   IP65
Operating Temperature Deg. C -20 to +60
Output Voltage Volts 13.8±0.2 @0A, >12 @50A
Water & vibration Resistant   Enclosure is sealed to protect from water and vibration.
Enable Switch Control   The converter can be controlled by a switch or relay on the enable (green) wire circuit. Connect to pack positive to enable.
Overheat Protection   Automatically reduces output current if the temperature is over 60°C, but does not shut down - this maintains power for your accessories.
Short Circuit Protection   Shuts down, then auto-resets after a short circuit is corrected.
