Avatar Instruments Inc A1P-24-30 Power Supply

The Avatar Instruments A1P-24-30 is a single‑phase SCR power controller designed to regulate AC power to heaters and other loads from a 208–240 VAC supply, rated for up to 30 A. It accepts a 4–20 mA control signal (typically sourced from a 5 V DC reference with a 250 Ω input) to adjust the output voltage from about 1% to 97% of the input. This model is part of Avatar Instruments' A1P series of SCR power controllers used in industrial heating and similar applications where precise AC power control is required. Soft‑start options exist in related codes (for example, A1P‑24‑60‑S05 demonstrates a 5 second soft start), enabling controlled ramp‑up when power is applied.
