The RT9-48V/1.4kW is a switched mode rectifier

(SMR) module that delivers up to 1.4kW of output

power (and up to 30A output current) into a 48V

nominal DC system. The RT9 suits AC supply

voltages between 208 and 240VAC but will also

operate at reduced power from supplies as low as

100VAC. The RT9 may be safely hot-plugged into

a live system for convenient system expansion or

module replacement.

Rectifiers convert power from an AC supply into

smooth DC, and are normally used in conjunction

with a battery to provide an uninterruptible DC

power system. A number of SMR modules (N) are

commonly used in parallel to deliver the required

power, with one or more additional modules (N+1)

providing redundancy.

The small dimensions of the RT9 allow high power

density in 300, 400, or 600mm deep 19-inch or 23-

inch racks. The addition of a supervisory and

control unit (CSU) allows a sophisticated power

system to be built with network connectivity and

remote asset management features.

Operating characteristics of the RT9-48V/1.4kW at 25°C, 230VAC, 50Hz unless otherwise stated:

Input AC

Voltage:

Single phase: Active, Neutral, and Earth.

Rated voltage range: 100 – 240VAC;

Rated voltage tolerance: 85 – 275VAC;

Maximum voltage before shutdown 300VAC;

Full output power available above 185VAC;

Reduced output power from 85 – 185VAC;

(Available power varies from 560W – 1400W);

At 100VAC, 680W available;

At 120VAC, 850W available;

Current:

9.5A RMS max line current at 185VAC;

7.5A RMS line current at 230 VAC;

Current limited to 10A or less below 185VAC;

Frequency:

45 - 66Hz;

Inrush Current:

< 9A RMS;

Soft Start:

Output current ramp-up time 8 seconds to 25A;

Harmonic Distortion:

Current THD < 5% typically at full output power

when operated with mains voltage THD < 2%;

Power Factor:

> 0.98 for >50% output power;

> 0.99 for 100% output power;

Reduced power factor above 275VAC

Protection:

Fully protected up to 440VAC;

Varistors provide surge protection;

Two internal fuses provided;

SMR is turned off if the AC voltage exceeds

~305VAC or falls to less than ~70VAC; SMR re-

activates when AC voltage is within approximately

83 – 285 VAC;

Input inrush limiting circuit prevents high surge

currents during a hot-plug installation;

Voltage Withstand Test:

1500VAC input to chassis for 1 minute;

(2200VDC 100% testing on production units for 2

seconds);

Efficiency:

> 90% typical from 50% to 100% output power;
