Description: New factory sealed, TDI Mercury MER12WRB-N54D00 (136874-N54D00) Rectifier Power Supply 1200W 54VDC. Please contact me if you are interested in used units as well as new or used enclosures for these power supplies. AC INPUT Voltage: 90—275VAC Over-voltage (tested to 300Vac) Frequency: 47-63Hz Peak Inrush Current: <20A Power Factor: 0.99 typical Efficiency: ~88% with 115VAC source, 50 to 100% load Hold-Up Time: 20mS min. Input Overcurrent: (internal) 20A Fuse DC OUTPUT Voltage: 54V Power: 1,200W Accuracy: ± 50mV Ripple & Noise: 1% V P-P Measured with 20Mhz Bandwidth Line Regulation: Less than ±0.25% Load Regulation: ±1.0% from no load to full load (droop load share) Parallel Use: May be paralleled with other like units for increased system output, redundant diode included Current Sharing: Slope program current share, (droop) Temperature Coefficient: < ±0.02% per°C Acoustic Noise < 55dBA at nominal input and full load ELECTRONIC ALARMS (Basic Set, others available) AC OK: low when AC input is in range Output OK: low if the output voltage is within 10% of the actual voltage set point (low=<.6V@1mA) (high=open collector (I<50μA) CAN Bus: available option VISUAL FAULT INDICATORS Output OK: A front panel Green “Output OK” LED will be lit if the unit’s output is within the acceptable range. ELECTRONIC CONTROL INPUTS Remote Inhibit: Application of a TTL input signal will cause the supply to shut down and an output OK fault alarm will be issued. (TTL High = Inhibit) Remote Program: Provides +9%, -27% of set point voltage with 0 to 5V control signal TEMPERATURE Normal Operation: -20 to +55°C High Temperature Operation: derate 10% per°C, 55 to 65°C Low Temperature Turn On: -40°C Minimum Storage / Transportation: -40°C to +85°C Humidity Operating: 5% to 95% RH non-condensing Storage: 0% to 99% RH non-condensing PHYSICAL DIMENSIONS Dimensions: 2U H88x W122 x D375mm (3.5 x 4.2 x 14.75”) Weight: 4kg (9lbs) AGENCY COMPLIANCE CE Marked: Low Voltage Directive only standards Electrical safety: IEC 60950-1, UL 60950-1 EMI (conducted): FCC Part 15, Sub-part J, class A and EN55022, class A EMI (radiated): Stand alone module tested to EN55022 Class B.
