• Embedded devices and instrumentation requiring 12 V DC
• Access control and security equipment

Key specifications

• Output voltage: 12 V DC
• Maximum output current: 2.9 A
• Maximum output power: 35 W
• Input type: AC mains to DC switching conversion
• Mounting style: DIN-rail compatible form factor

How to use

Install the unit on a DIN rail inside a suitably ventilated control cabinet and make AC input connections according to local electrical codes. Connect the 12 V DC output to the load, observing correct polarity. Verify that the combined current draw of connected devices does not exceed 2.9 A and that the ambient temperature and ventilation meet the supplier's operating conditions. Perform initial testing with multimeter measurements to confirm steady 12 V output before connecting sensitive equipment.

Usage recommendations

For reliable long-term operation, avoid continuous loads at the maximum rated current without adequate ventilation and periodic inspection. Use appropriately rated wiring and fuses on both input and output sides, and install surge protection if the supply is exposed to unstable mains. Regularly check terminal tightness and ambient temperature to maintain stable output voltage.
