The SITOP PSU6200 6EP3321-7SB00-0AX0 is the most compact power supply in the Siemens DIN rail lineup: 25mm wide, 100mm tall, 88mm deep, and weighing just 0.19kg. It delivers a regulated 12VDC output at up to 2A continuous for small-scale automation, access control, security camera, and IoT gateway applications where panel space is extremely limited and 12V is the native operating voltage.

Designed for Fast Installation

Push-in spring terminals on both the input (L, N, PE, accepting 0.5-4mm²) and output (+, -, 0.5-2.5mm²) eliminate screwdriver torque checks during commissioning — wire, push, done. The wide-range input (85-264VAC, 47-63Hz, also 110-275VDC) auto-adapts to any global mains standard. A built-in 3.15A input fuse and inrush current limiting (45A max at 25°C) simplify upstream circuit breaker coordination. A green LED indicates "12V OK" status.

Reliability Features

The PSU6200 platform uses a robust metal housing rather than plastic — better heat dissipation and impact resistance in industrial service. Mains buffering exceeds 150ms at 230VAC, significantly longer than the 20ms typical of industrial power supplies, giving downstream devices more time to ride through grid disturbances. Short-circuit protection with constant-current limiting and automatic recovery, plus overvoltage protection, are standard. The operating temperature range spans -25°C to +70°C with convection cooling.
