DTB-R232
230W redundant power supply

Datasheet

Specifications
Input Voltage:
90~130VAC or 180~260VAC
Input Frequency:
47~63Hz
Inrush Current:
Not exceed 30A at 115VAC input or 60A AC input, at cold start 25°C
Load Range:
When all outputs are in 60% rated load condition, the +5V output is set between 4.98~5.02V while all other outputs are within the specified voltage accuracy range
Ripple And Noise:
Peak to peak ripple and noise for +5V, output is < 50mV, and < 100mV for +12V, -12V, -5V outputs at rated load, 115/230VAC
Line Regulation:
< +/-1% for each output at rated load and +/-10% of 115VAC or 230VAC input voltage change
Load Regulation:
The output voltage load regulation is less than the value on the table when subjected to +/-40% change on each output load from 60% rated load, and while all other outputs are at 60% rated load
Hold Up Time:
> 16ms at 115VAC input and rated load measured from the last AC line charging pulse to the point when +5V drops to +4.75V
Output Power:
The total DC continuous power is whthin 230W at < 30°C ambient temperature
Power Good:
When turned on, the signal goes high 100~500ms after all output DC voltages are within regulation limits
Power Redundancy:
This power supply has power redundant capability
Efficiency:
> 70% at rated load
Altitude:
10,000 feet
Protection
Built-in over voltage protection circuit shuts down the outputs to prevent damage. Trip point of crowbar circuit is between 5.7~7V; latch off mode against short circuit or over load conditions AC line ON/OFF cycle recovers unit from fault conditions
Temperature:
Operating: 0~40°C
Storage: -40~+75°C
Humidity:
Operating: 5~95%; non-condensing at 40°C
Connectors:
AC: One AC input socket
DC: O1 DIN 41612 C96
Dimensions:
14.0 x 15.0 x 8.62 cm +/-5mm tolerance
MTBF:
235,743 hrs.

Safety Standards
Safety:
UL 1950, CSA 22.2 No.234, VDE EN 60 950
EMI:
FCC Class B, EN55022B
EMS:
Level 3 of IEC-801, 802, 803, 804
