Power Supply

Siemens 6EP1333-2BA20 is a SITOP PSU100S series stabilised industrial power supply designed for reliable and efficient operation in demanding environments.

• Input voltage: 120/230 V AC (selectable, automatic range detection)

• Input voltage range: 85–132 V AC (120 V mode), 170–264 V AC (230 V mode)

• Output voltage: 24 V DC (regulated, adjustable between 22.8–28 V DC)

• Output current: 5 A (nominal, up to 6 A at reduced temperature)

• Output power: 144 W (max)

• Mounting: DIN rail (35 mm), compact and robust design

• Protection: IP20 rating for basic ingress protection; overcurrent, overload, short-circuit, overvoltage, and overtemperature protection

• Efficiency: 88%

• Parallel operation: Not specified for this model; typically, SITOP PSU100S units do not support parallel operation

• Certifications: CE, cULus (UL/CSA), ATEX, IEC compliant

• Operating temperature range: -25 °C to +70 °C (some sources state -10 °C to +70 °C, but -25 °C is official for this model)

• Dimensions: 50 mm (width) × 125 mm (height) × 120–125 mm (depth)

• Weight: Approx. 0.8 kg (varies by source)

• Connection: Screw terminals for secure wiring

• Additional features: Galvanic isolation between input and output; green LED status indicator; signalling relay contact for remote monitoring ("output voltage OK"); low ripple and noise; high immunity to interference

This power supply is suitable for industrial automation, control panels, PLCs, sensors, actuators, and other applications requiring stable and reliable DC power
