Extreme low profile: 14mm * 27mm * 46/63mm @ 28 grams in ABS plastic housing.
Nameplate input: 15V to 85V DC (AKA "72v")
Nameplate output: 12V 1A (12w)
Conversion efficiency: >93%
No-load current loss: 25mA
Waterproof rating: IP67
Operating temperature: -40 to 40 degrees, to 80 degrees on lower current load.
Protection: Over-current / Over-voltage / Over-heat / Short-circuit.
No reverse polarity protection.
Note: 72V systems will exceed 85v when fully charged and under regenerative braking. This is outside of the specification of this buck converter, however within tolerance depending on duration, load and environmental factors. eScootNow has nameplate buck converters to 90v for more demanding applications, however these are physically larger than this product.
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.
