CAUTION! Always set voltage and current limits before connecting sensitive equipment.

Specifications

Controls and Settings

Front panel controls: Power switch, voltage adjustment, current limit, output terminals.

Display: Shows output voltage and current simultaneously. Voltage adjustment: Use coarse and fine controls for precise setting. Current limiting: Adjust to protect connected devices. Output enable: Switch to activate/deactivate output.

Protection settings: Overload protection automatic, thermal protection built-in, short circuit protection immediate shutdown.

Connecting Devices

Output terminals: Red for positive, black for negative/ground.

  1. Ensure power is off before making connections.
  2. Connect positive lead to red terminal.
  3. Connect negative lead to black terminal.
  4. Set desired voltage and current limits.
  5. Apply power and enable output.

Tip: Use appropriate wire gauge for expected current load.

Operation Modes

Supports constant voltage and constant current operation.

  1. Constant Voltage: Maintains set voltage regardless of load changes.
  2. Constant Current: Maintains set current limit when reached.
  3. Display modes: Shows actual output voltage and current.
  4. Protection modes: Automatic shutdown on overload or short circuit.
  5. Fan operation: Automatic temperature-controlled cooling.

WARNING! Do not exceed maximum ratings. Monitor temperature during extended operation.

Safety Features

Overload Protection: Automatic shutdown when current limit exceeded. Thermal Protection: Shuts down if internal temperature too high. Short Circuit Protection: Immediate shutdown on output short. Isolation: Input-output isolation for safety.

Care & Maintenance

Unplug before cleaning. Keep ventilation openings clear. Use compressed air to remove dust.

CAUTION! No user-serviceable parts inside. Refer servicing to qualified personnel.
