Delta ES150/EST150 150W DC Power Supplies

The ES150/EST150 is a 150W programmable DC power supply designed for laboratory and industrial applications. It offers flexible output with constant power characteristics, ensuring long life at full power and excellent dynamic response to load changes. The EST150 variant provides three independent floating outputs, each with its own ON/OFF switch.

The ES150 series includes models with the following output ranges:

• ES015-10: 0–15V at 0–10A

• ES030-5: 0–30V at 0–5A

• ES075-2: 0–75V at 0–2A

• ES300-0.45: 0–300V at 0–0.5A

• EST150: Triple output with 0–10V at 0–5A and two 0–20V at 0–2.5A

These models provide flexibility to meet various application requirements.

ES150 Key features include:

• Low Ripple and Noise: Ensures clean and stable output.
