Conquering Input Voltage Challenges: Wide Range & Resilience
One of the SITOP PSU200M's most significant strengths is its incredible input voltage flexibility:
Input 1: Operates seamlessly from 85 V AC to 264 V AC, covering standard single-phase ranges worldwide, including fluctuations.
Input 2: Handles an impressive 176 V AC to 550 V AC, making it suitable for specific industrial applications or regions with higher line voltages.
Wide-Range Input: Yes, this unit automatically adapts within its vast input range.
Mains Buffering: Provides critical ride-through during brief power dips, offering min. 25 ms of buffered power at full rated load.
Frequency Tolerance: Works reliably within 47 Hz to 63 Hz, accommodating common grid variations.
Precision Output Performance: Stable 24V DC Under Load
The PSU200M doesn't just deliver power; it delivers quality power:
Output Voltage: 24 V DC (adjustable from 24 V to 28.8 V).
Stability: Exceptional ±3% total static tolerance.
Minimal Variation: Low static mains compensation (~0.1%) and static load balancing (~0.1%) ensure consistent output despite input or load changes.
Clean Power: Very low residual ripple (max. 50 mV peak-peak) and controlled spikes (max. 200 mV peak-peak @ 20 MHz) protect sensitive electronics.
Full Power Delivery: Rated for 10 A continuous current, delivering up to 240 W of active power. Output is continuously adjustable from 0 A to 10 A.
Built-In Protection & Robust Operation
Engineered for industrial longevity and safety:
Overload/Surge Handling:
Constant Overload (Startup): Handles 12 A typically during startup surges.
Short-Term Overload (Operation): Withstands 30 A typically during operational short-circuits.
Overload Duration: Maintains output voltage under short-circuit conditions for min. 25 ms.
Inrush Limiting: Controlled switch-on with max. 35 A inrush current (+25°C) and low I²t value (4 A²·s) to prevent tripping upstream fuses.
Status Monitoring: Clear Green LED indicates "24V O.K." status.
Startup Behavior: Defined turn-on delay (1 s) and voltage rise time (50 ms) for controlled system initialization.
Scalability for Demanding Applications
The SITOP PSU200M offers flexibility beyond the single unit:
Parallel Operation: Up to 2 units can be paralleled for redundancy (N+1) or to achieve higher output currents (up to 20 A), enhancing system availability and power capacity without needing a completely different PSU model. This is a crucial feature for mission-critical systems.
