S-75 Switching Power Supply

The S-75 Series provides four single-output DC versions: 5V, 12V, 15V and 24V, with rated output power from 75W to 76.8W.

The S-75 is an enclosed AC/DC switching power supply designed for stable DC power delivery in industrial control equipment, electronic systems and general power supply applications.

The series provides switch-selectable AC input, 105°C output capacitor design, soft-start current, built-in EMI filtering, overload and short-circuit protection and 100% full-load burn-in testing.

Selectable AC Input

85–132VAC or 170–264VAC switch-selectable input, with 240–370VDC input support.

Four Output Versions

Available in 5V, 12V, 15V and 24V DC output models.

Compact Enclosed Design

159 × 97 × 38 mm enclosed design for industrial and electronic equipment.

Protection Functions

Built-in overload and short-circuit protection with automatic recovery after the fault is removed.

Built-in Protection Functions

Overload Protection

Protection operates at approximately 105%–150% of rated output power. Output power limiting protection is used, and the power supply automatically recovers after the abnormal load condition is removed.

Short Circuit Protection

Built-in short-circuit protection helps protect the power supply during abnormal output conditions. Normal operation can resume after the fault condition is removed.
