12V 10A (120w) Buck Converter (30-90v input)

Well suited for 72v systems to withstand peaks to 90v when fully charged and under regenerative braking. This is a popular alternative to replace factory MiniMotors buck converters that can fail under these conditions (and damage lights etc on the 12v output circuit).

Compact profile: 22mm * 40mm * 75/58mm @ 105 grams in ABS plastic housing.

Nameplate input: 30V to 90V DC (AKA "60/72v")
Nameplate output: 12V 10A (120w) which is pretty impressive given the size of the casing

Conversion efficiency: >93%
No-load current loss: <100mA

Waterproof rating: IP68
Operating temperature: -40 to 40 degrees, to 80 degrees on lower current load.
Protections: Over-current / Over-voltage / Over-heat / Short-circuit.
Reverse polarity protection not specified

eScootNow hobbyist tips on Buck Converters:

Remember with wide voltage input Buck Converters, ensure you accommodate circumstances that would otherwise deplete battery to damaging reserve levels. I typically run a relay when implementing non-ACC (accessory) switched buck converters. Relay or ACC blue wire on ACC buck converters can take input off the controller's light switch output wire or throttle/display power-on. This isolates the buck converter when scooter is powered off.

It is best practice to keep the regulated circuit (secondary/output) of the Buck Converter isolated from the native DC circuit of your scooter. Do not bridge the two. This may also apply to the -ve of the regulated circuit, I'm yet to investigate that.
