Technical Parameters & Selection Guide

Selection Criteria:

Choose the PS 1000 WR 011 when your application requires 120 VAC input compatibility. For 230 VAC installations, specify the WR 012 variant. Calculate total load current including 20% safety margin for future expansion. For redundant configurations, use diode decoupling modules (sold separately) to enable hot-swap capability. Ensure adequate ventilation with minimum 50mm clearance above and below the unit.

Frequently Asked Questions

How do I configure redundant power supplies for safety systems?
Use diode decoupling modules rated for 40A minimum. Connect both supplies to a common DC bus through individual diodes. This configuration provides automatic failover if one supply fails while preventing reverse current flow.

What is the maximum cable length for 24V DC distribution?
For 40A loads, use minimum 10 AWG (6mm²) wire. Maximum recommended length is 50 meters to maintain voltage drop below 2%. For longer runs, consider higher voltage distribution with local DC-DC converters.

Can this power supply operate in hazardous area classifications?
The PS 1000 WR 011 is IP20 rated for general industrial use. For Class I Div 2 or ATEX Zone 2 applications, install in approved purged enclosures with proper certification documentation.

Does the unit include EMI filtering for sensitive instrumentation?
Yes, integrated EMI/RFI filtering meets EN 55011 Class A and FCC Part 15 Class A standards. Additional external filtering may be required for medical or laboratory applications with stricter noise requirements.

What maintenance intervals are recommended?
Inspect terminal connections quarterly for tightness. Clean ventilation openings semi-annually. Electrolytic capacitors have 10-year design life at rated temperature; consider preventive replacement after 8 years in critical applications.

Is the output voltage adjustable for non-standard applications?
Yes, internal trim potentiometer allows ±10% adjustment (21.6V to 26.4V). Factory calibration is set to 24.0V ±0.2V. Adjustment requires multimeter and should be performed by qualified personnel.
