Siemens 6EP3436-8SB00-0AY0 SITOP PSU8200 Power Supply 3AC 24VDC 20A

The Siemens 6EP3436-8SB00-0AY0 is a SITOP PSU8200 stabilized DIN-rail power supply with 3-phase 400-500 V AC wide-range input and regulated 24 V DC / 20 A output (480 W continuous). Provides soft-start without output voltage overshoot, adjustable 24-28 V output via potentiometer, and "24 V OK" signaling via a green LED plus relay contact.

• Soft-start: No Vout overshoot at power-on
• Isolation: Controlled, isolated DC output

Features and benefits:

• Wide-range 3-phase 400-500 V input - global infeed flexibility without taps
• 15 ms mains buffering - tolerates brief power dips without output dropout (longer than the 6 ms of PSU300S)
• Higher precision than PSU300S (0.1 % / 0.2 % vs 1 % / 2 %) - cleaner output for sensitive sensors and measurement loops
• "24 V OK" signaling via relay NO contact - direct PLC integration
• Soft-start - no overshoot at power-on
• Adjustable 24-28 V - cable voltage drop compensation

Applications:

• 24 V DC supply for industrial control panels and PLCs needing 480 W
• Sensor and measurement loops requiring low ripple and tight regulation
• Machine builder applications with 3-phase 400/480 V infeed
• Plants requiring long mains buffering (15 ms) for ride-through during line disturbances
