The AKL series 4U high-frequency switching power supplies feature high performance, stability, reliability, compact size, and lightweight, and come with essential protection functions like overvoltage, current limiting, and short-circuit protection. Voltage, current, and overvoltage protection values can be pre-set before loading, and all set parameters can be easily checked during operation. The process is simple and convenient.

Product Features:
Voltage and Current Pre-Setting: The panel features pre-set buttons for pre-determining voltage and current values.
Voltage and Current Stabilization: Continuously adjustable from zero to rated value, automatic switching between voltage and current stabilization
Overvoltage Protection: The machine will automatically lock after protection and unlock automatically upon restart.
Overcurrent Protection: Rated current output overload protection, short-circuit protection (output shutdown after short-circuit, optional)
Short-circuit Protection: Allows for long-term short-circuit or short-circuit startup in any state
Short-circuit Alarm: Audible and visual power alarm when an output short-circuit occurs.
Pulse Operation: Can be configured with a timer controller to form a DC pulse power supply (optional)
Communication: Standard RS485 communication interface
Special specifications and features are customizable.
