3Pcs Constant Current Power Supply Kit DIY Regulated DC 0-30V 2mA-3A Adjustable
Installation instruction: http://img.banggood.com/file/products/20180108011904POW-CC-Power-supply.pdf Feature: This is a high quality regulated power supply kit with adjustable output voltage from 0-30V and current from 2mA to 3A. When the output current is greater than the set current, LED light, the circuit automatically switches to constant current mode, which can effectively protect the load. Parameter: Model: POW-CC PCB size: 92.4 x 80mm Input voltage: AC 15-24V, maximum 24V Input current: 3A Output voltage: 0-30V Output current: 2mA-3A Voltage ripple: 0.01% Fan voltage: DC24V Want to get 30V / 3A output, the need to use more than 100W transformer, and ensure Q4 has good cooling. Note: This power supply can only use AC as input Input AC 15V, the output DC 0 - 18V Input AC 20V, the output DC 0 - 25V Package includes: 3 x Constant Current DC Power Supply Kit
