DTB-R232

230W Redundant Power Supply

Safety Standards

Features

*Input Voltage: 90~130VAC or 180~260VAC

*Input Frequency: 47~63Hz

*Inrush Current: Does not exceed 30A at 115VAC input or

*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 < 30oC ambient temperature

*Power Good Signal: 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

(storage)

*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: UL 1950 / CSA 22.2 No.234 / VDE EN60950

*EMI: FCC class B / EN55022B

*EMS: Level 3 of IEC-801, 802, 803, 804
