Grin Tech 12V 20 Watt Output Rugged DC-DC Converter, for 24V- 48V Batteries


More Views

12V 20 watt output DC-DC converter, for 24V, 36V, and 48V battery packs. Made in Vancouver

Rugged and compact and completely potted in epoxy leaving no concern of water, dust or snow damage or of exposed metal pins shorting out against the bike frame.

Comes in slim 42x23x12mm package with about 60cm of 18 AWG cable on the input side, 90cm at the output plus another 30cm attached to the included mating plug. 

Uses 5.5 x 2.1mm DC plug on output.

When drawing close to the maximum load, the DC-DC converters will get quite hot so it is best to keep them exposed to air flow under high load situations rather than tucked into a padded bag. They have an internal temperature shutdown to protect the internal circuit but by that point the block of cheese sitting next to them stuffed inside your pannier could be a little melted.
