ERPF-400-24 Mean Well 24VDC 400.8W 16.7A Enclosed Power Supply

Description

Mean Well ERPF-400-24 is a 400.8 W enclosed switching power supply featuring a 24 VDC output, 16.7 A rated current, and physical dimensions of 220.4 x 130 x 48 mm. The unit incorporates an active power factor correction (PFC) circuit and is housed in a semi-potted aluminum casing designed for rain splash and dust protection. Internal architecture includes high-efficiency power conversion stages, a terminal block interface for electrical connections, and an LED indicator for operational status. The hardware is engineered for cooling by free air convection without the requirement for internal fans.
