Portable Adjustable Power Supply V3.1 - Variable Voltage Bench Power Source for Electronics Repair, Lab & DIY Long

Descriere Portable Adjustable Power Supply V3.1 - Variable Voltage Bench Power Source for Electronics Repair, Lab & DIY Long

The spring leaf of the 18650 battery holder is relatively high. This package does not include batteries. It is recommended to adjust the spring leaf slightly with pliers before installation for easier battery mounting and removal.
When removing the battery, pry it gently from the negative terminal side to avoid short circuit caused by contact of the positive terminal.
The long banana plug can clamp wires, while the short one cannot. All other features are identical. This product uses a 4mm banana socket, compatible with all standard 4mm banana plugs. For self-made use, lantern-type banana plugs are recommended for better performance.
Input Voltage: 5-20V, built-in 2 pieces of 18650 batteries. Supports external power supply via USB PD, or XT60.
Note: The power supply can work to 24V maximum, but some switching power supplies may burn the power chip. If 24V operation is required, prepare an extra power board for testing; the board is replaceable if damaged.

Output Voltage: 1-36V, automatic step- and step-down. 1-36V output is achievable within 5-20V input range.
Output Current: 0.3-6A adjustable, maximum 6A. Actual current is limited by output power and input power.
Output Power: Recommended within 120W, 200W. Do not operate continuously at power for long hours, otherwise the power switching tube may be burned easily.
