The Single-Phase Isolation Control Transformer DG-4000VA acts as the "power firewall" for DCS cards, isolating them from grid harmonics, surges, and common-mode interference.

 

The DG-4000VA uses a dual-winding isolation design, completely separating the primary and secondary circuits. This blocks grid harmonics, resulting in a very clean voltage output from the secondary side. The iron core is also fitted with a shielding layer to block common-mode interference, preventing false actions in the sensitive DCS cards.

 

The input side of the DG-4000VA is equipped with a surge protector that instantaneously dissipates energy during grid surges, protecting the transformer and downstream equipment. Output voltage accuracy is maintained within ±1%. Even if grid voltage fluctuates, the DG-4000VA stabilizes the output. During installation, the DG-4000VA must be physically separated from power transformers, and input/output cables must be routed separately with reliable grounding. Output voltage is measured monthly to check for fluctuations. If harmonics are high, the grid-side filter should be checked. The DG-4000VA reliably serves as the "firewall," providing clean power to precision equipment.
