Installation

Unpack and inspect contents. Ensure proper ventilation and mounting.

Choose location: Well-ventilated area, away from heat sources and moisture.
Mount unit: Use provided brackets for 19" rack or secure to stable surface.
Connect AC power: Use appropriate power cord for your region.
Connect DC outputs: Use recommended gauge wire for each channel.
Connect remote interface: Optional RS-485 connection for monitoring.

WARNING! Unit contains high voltages. Disconnect power before installation. Ensure proper grounding.

First-Time Setup

Power on unit; initialize system parameters.

Power up: Turn main switch ON; observe startup sequence on display.
Set output voltages: Use front panel controls to configure each channel.
Configure protection limits: Set OVP, OCP values for each output.
Enable remote interface: Configure address and communication parameters if used.
Save configuration: Store settings to non-volatile memory.

CAUTION! Verify load requirements before applying power. Start with minimum loads.

Default password for calibration: 1234.

Connecting Devices

AC Input: Standard IEC connector. DC Outputs: Screw terminals (+, -, sense). Remote Interface: RJ-45 connector.

Turn OFF power before making connections.
Connect loads: Use appropriate wire gauge for current requirements.
Use sense connections for remote voltage sensing on critical loads.
Connect communication cable: Use shielded twisted pair for RS-485.
Verify polarity before applying power.

Tip: Keep DC output wires as short as possible to minimize voltage drop.

Operation Modes

Supports constant voltage, constant current, and power sequencing modes.

Constant Voltage: Default mode; maintains set voltage regardless of load.
Constant Current: Automatically switches when current limit reached.
Sequencing: Programmable turn-on/turn-off delays between channels.
Tracking: Multiple channels can track each other's voltage.
Remote Control: Via front panel, RS-485 interface, or analog control inputs.
Monitoring: Real-time display of voltage, current, power, temperature.
Data Logging: Internal memory stores fault events and operating parameters.

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

Safety Features

Over-Voltage Protection: Automatically shuts down output if voltage exceeds set limit. Over-Current Protection: Limits current to safe value. Over-Temperature Protection: Reduces output or shuts down if overheated. Short-Circuit Protection: Current limits to protect unit and load. Fan Failure Detection: Alerts if cooling fan stops.

Maintenance & Cleaning

Disconnect power before maintenance. Clean exterior with dry cloth; clean ventilation openings regularly.

CAUTION! No user-serviceable parts inside. Do not open casing. Refer servicing to qualified personnel.
