Dual Linear DC Power Supply

These compact DIN rail mounted dual power supplies provides reliable, regulated and current limited DC power for many process control applications. The two supplies are isolated from each other. The outputs are regulated to within 0.5% from no load to full load from 230 or 115 VAC. Linear voltage regulation ensures a low noise DC output. Indefinite short circuit protection is provided at about 10% more than the rated output current. An internal mains fuse and MOVs provide protection against power surges and spikes.

Applications:

• Powering of process transmitters.
• Low noise strain gauge or loadcell excitation.
• Providing a low noise, regulated, DC supply to any equipment.
• Generating a split power supply for special applications.

Outputs:

• 2 x 24 V (19-28V) @ 30 mA,
• 2 x 18 V (15-21V) @ 40 mA,
• 2 x 15 V (12-18V) @ 50 mA,
• 2 x 12 V (10-14V) @ 60 mA,
• 2 x 10 V (9-11V) @ 80 mA,
• 2 x 5 V (4.5-5.5V) @ 100 mA.
