  • Full load temperature rise: 45C
  • Protection: Over-current, Over-temperature, Short-circuit protection,
  • Auto-recovery when the device is back to normal operating parameters
  • Input Reverse Polarity Protection: NONE (Please Series diode at the input port.)
  • Weight: 40G (~1.5 oz)
  • Size: 66 x 60 x 22mm (2.6 x 2.36 x 0.87 inches) L x W x H
  • Input and output wire lengths: ~13cm (~5 inches)
  • Output connector: Bare wire
  • The red and black leads are the + and - inputs, and the yellow and black leads are the + and - outputs

Operating Notes:

As with any DC-DC converter, the input DC power supply powering this converter must be capable of providing the maximum power drawn by your load. If the input supply is not capable of providing the power, the converter will fold back the output voltage as necessary. Example: If your load draws 3A at 5V (15W), and the input supply is only capable of providing 12V at 1A (12W), the maximum output voltage the converter will deliver is 4V (12W/3A).
