• Maximum output current: 120 A
• Output type: regulated DC suitable for continuous operation
• Typical use environment: laboratory, workshop, service bench
• Cooling concept: designed for thermal management during high-load operation

How to use

Connect the supply to the device under test using appropriate gauge cabling and secure terminals. Set the desired output voltage within the 12.6–14.8 V range using the front-panel controls or interface, then set current limiting according to the device specifications to prevent overload. Monitor voltage and current readings during testing and adjust settings as required. When performing prolonged high-current tests, ensure adequate ventilation and observe thermal indicators or fans as provided by the unit.

Recommendations

Use sufficiently thick, low-resistance cables and secure connections to minimise voltage drop at high currents. Verify current limit settings before applying power to protect devices and wiring. Allow the unit to cool between extended high-current cycles if thermal limits are approached, and operate the supply in a ventilated area to maintain stable performance.
