UL/EN/IEC60950
Protection
characteristics
Over/under-voltage protection
Input under-voltage protection point: 80V ± 5V
Input over-voltage protection point: 305V ± 5V
Output over-voltage hardware protection point: 58.5V ~ 60V
Output over-voltage software protection point: 56V ~ 59V (it can be
configured through the controller)
Over-temperature protection
The rectifier will shut down, owing to over-temperature
Mechanical
parameters
Size (Height × Width × Depth)
43.6mm × 85.1mm × 252.5mm
Weight
≤ 2.0kg
Others
Efficiency
> 95.5% (peak value)
Current sharing
The current sharing error of the rectifier is smaller than ±0.9A
Temperature coefficient (1/°C)
0.01%
Dynamic response
Response time:
≤ 200μs; Overshoot: ≤ 5%
Start-up time (select the
startup mode through the
controller)
Normal startup: the time delay from AC power-up to rectifier output is less
than 5s
Gradual onset of output: The start-up time can be set through the
controller. The settable range is 8s ~ 124s, and the precision is not bigger
than ±10%
Noise
≤ 50dB (A)
Surge protection
EN61000-4-5
Cooling method
The fan uses the the stepless temperature control to adjust the fan speed.
The speed increases with the rise of the temperature
Insulation resistance
Apply a test voltage of 500Vdc. The insulation resistances between DC
circuit and earth, AC circuit and earth, and AC and DC circuits are all not
less than 5
MΩ
Insulation strength
AC input terminal to enclosure: 2121Vdc.
AC input terminal to DC output terminal: 4242Vdc.
DC output terminal to enclosure: 707Vdc.
For all the three tests above, there should be no breakdown within 1min,
with steady state leakage current no bigger than 1mA
MTBF
≥ 120000 hours
