M550129-01 Rev AG
Parameter
Specification
Power Factor
(at full rated load; 50/60 Hz); contact factory for power factor of specific models
PFC models: 10V-30V, 50V,
1000V, and models with optional
modification, “PF”
0.90, typical, for all AC input ratings; with passive power factor
correction (PFC)
Non-PFC models: 40V-800V
0.75, typical, for 208/230 VAC input;
0.72, typical, for 380/400 VAC input;
0.69, typical, for 440/480 VAC input;
power factor is not solely determined by power supply input
characteristics, but is dependent on the level of DC output
power and interaction with the source impedance of AC mains.
Efficiency
87%, typical, at full load, nominal AC line
Hold-Up Time
1/2 cycle, typical, for loss of all three phases (6.4 ms, typical for
800V/1000V models); 3 cycle, typical, for loss of one phase;
sustained missing phase will result in shutdown of the output.
Rated Output Power
4-15 kW for 3U chassis for 10V-30V models;
5-15 kW for 3U chassis for 40V-1000V models;
20-30 kW for 6U chassis for 40V-600V models;
maximum output power is the product of the rated output
voltage and current; for specific values refer to Section 1.2.3.
Load Regulation
(specified for ±100% rated load change, at nominal AC input voltage)
Voltage
±0.05%, maximum, of rated output voltage for 10V- 30V
models;
±0.02%, maximum, of rated output voltage for 40V-1000V
models
Current
±0.1%, maximum, of rated output current
Line Regulation
(specified for ±10% change of nominal AC line voltage, at constant load)
Voltage
±0.05%, maximum, of rated output voltage for 10V- 30V
models;
±0.01%, maximum, of rated output voltage for 60V-1000V
models
Current
±0.05%, maximum, of rated output current
Temperature Coefficient
Voltage
±0.02%/
C, typical, of rated output voltage
Current
±0.03%/
C, typical, of rated output current
Stability
±0.05%, typical, of rated output voltage or current, over 8 hrs at
fixed line, load, and temperature, after 30 min warm-up
Output Voltage Ripple/Noise
Refer to Ripple/Noise specifications in tables of Section 1.2.3.
Load Transient Response
1 ms, typical, to recover within 0.75% of rated output voltage for
load step change of 50% of rated output current
Output Voltage Rise Time
(with rated load, resistive; current
rise time same)
10 ms, maximum, from 10-90% of programming change from
zero to rated output voltage for 10V-30V models;
100 ms, maximum, from 5-95% of programming change from
zero to rated output voltage for 40V-1000V models;
