Module input IN- cannot short circuit with output OUT-, otherwise constant current function will be invalid. 2. Please make sure that the power of the power supply is greater than the power required by the output load. Please reduce the power when the module is extremely hot.

I power it with the charger "brick" from a retired laptop PC, capable of as much as a couple amps at 25VDC. The specifications don't make it clear, but you independently set the maximum output current and output voltage using the on-board 10-turn pots while monitoring it on the display. For example when charging a lithium-ion battery, its specs might suggest a the maximum charging current of 0.5A and maximum output voltage of 4.2V. So first, you set the open-circuit voltage to 4.2V. Turn the output current to minimum and connect the batery. Assuming the battery is pretty well discharged, when you first connect it you could potentially sink as much as several amps but that would hurt the battery. No problem, you've set the current to minimum (a few mA). When you connect the battery, turn up the current to 0.5A; the voltage will rise as you turn up the current, probably settling around 3.5V. (I am assuming that your power source will easily supply the required power.) As the battery charges, the voltage will gradually increase to 4.2V while the current stays at 0.5A. But once the voltage gets close to 4.2V the current will start to taper off. If left for several hours the voltage will still be at 4.2V but the current will be only a few mA. So the supply acts like constant current, then transitions to constant voltage. I hope this answers your question. I haven't seen any evidence of loss of control over either output voltage or current. FYI it's worthwhile to experiment with the unit connected to an output load resistor first, to get an understanding of which buttons to press to read the desired values. From memory, you can read input voltage and current, temperature of the heat sink in F or C, and output voltage and current. And you can also read output voltage independent of supplying power to the load (i.e. it can act like a voltmeter). **Q: What does opp error mean?** A: Dear customer, OPP:Over-power Protection When output power reaches 35W, OPP will be enable. Best regards. **Q: Is there an operating/owners manual** A: Good day.

This morning I needed to run 2 12V PC fans from a USB 2.0 port. It worked drawing around 400mA. ## Frequently Bought Together - DROK DC Buck Converter, 5.3V-32V to 1.2V-32V 12A Adjustable Power Supply, 5v 9v 12v 24V 30V 32V Step Down Voltage Regulator with LCD Display Volt Transformer Reducer CC CV for RV Solar Panel Golf Cart - APIELE 16mm Latching Push Button Switch 12V DC On Off Black Shell with LED Angel Eye Head for 0.63" Mounting Hole with Wire Socket Plug Self-Locking (Blue/Black Shell) - ARRAROWN ZK-1002T 2.0 Channel Bluetooth 5.0 Amplifier Board 200W HiFi Subwoofer Audio AMP with Treble and Bass Control BT and AUX Inputs, DC 12-24V 2.0 Channel Stereo AMP Module for DIY Speakers --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/428330308-adjustable-voltage-regulator-drok-dc-to-dc-5-3v-32v](https://www.desertcart.com.pa/products/428330308-adjustable-voltage-regulator-drok-dc-to-dc-5-3v-32v) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-09-13*
