## Description

Wiring: OUTPUT+ to LOAD+, OUTPUT- to LOAD-; INPUT+ to BAT+, INPUT- to BAT- Reminder: Never reverse the polarity. Use the enough big cable to avoid the voltage drop. Never connect to solar panel or wind turbine. Never charge the battery. Keep good air convection. Daygreen P/N: B30-3648-12A Efficiency: 95% Input Voltage: 30-60V DC Output Voltage: 12VDC Output Current: 30A No-load current: <0.1V Ripple: 200mVp Line Regulation: ±0.2% Load Regulation: ±0.2% Voltage Accuracy: ±1.5% Enclosures: IP68 Dimension: 100*80*39mm Net Weight: 0.5kg Case Operating Temperature: -40~85°C Certificates: CE Rohs Warranty: 3 years MTBF: 100,000 hours Application: 36V DC battery of vehicles as input power to 12VDC appliances as output load. QuestionsHow to choose the correct current for loads? For example, if the max current of your load device is 10A, then choose 10A/0.7=14.28A at least for resistive loads according to international standard. If the load device is motor or compressor, then you may choose 10A/0.5=20A according to real testing result since the motor and compressor starting current may be 2-3 times than nominal current.

Review: Works for kayak, converts eBike 48v battery to 12v for trolling motor - The specifications are good, and it works well in my application. I have a 48v ebike battery, then this device converts to 12 v, then a 12v PWM speed controller, finally connecting to the trolling motor. The seller says not to directly connect it up to a solar panel, so I couldn't resist and did (48volts max). It still works great without the battery at all ! But it does require you to reduce via PWM the load (ie., speed) of the motor if a cloud comes over or the motor stops (due to MPPT solar output voltage not correct). Stronger than expected unit.
Review: Great product - Works as it should and the price is good. Installed on a 36 v golf cart, stepped voltage from 36 to 12 perfectly.

Works as it should and the price is good. Installed on a 36 v golf cart, stepped voltage from 36 to 12 perfectly.

### ⭐⭐⭐⭐⭐ Works perfect for a Club car Precedent 48volt
*by A***R on October 6, 2020*

Easy hookup on my 2015 Club Car Precedent 48V. I used it to reducer 48V to 12V for a Cell Phone USB connection port. Super easy way to reduce for adding acc to your golf cart.
