OPERATING MANUAL

11.2 The PowerCassette is CE marked to indicate conformance to the

European Union’s Low Voltage Directive.

11.3 Input conducted EMI meets FCC20780 part 15J Curve B and EN55022

Curve B.

11.4 The input immunity, conducted, meets the following. Input fast transients, line-

to-line, meet EN61000-4-4 Level 3; input surges, line-to-line, meet EN61000-

4-5 Level 3; and input surges, line-to-ground, meet EN61000-4-5 Level 4.

12.0 OPERATING INFORMATION

12.1 Input Voltage and Connection. The PowerCassette operates off world-

wide AC input voltages in the range of 85 to 264 VAC at 47 to 63 Hz. The

three-wire AC connection is made to pins 22-24 on the Positronics connec-

tor. See the connector diagram and Pin Connections table in Figure 5a.

12.2 Output Connections. The output voltage is provided on pins 1 to 6 of the

Positronics connector. Three pins (1 to 3) are connected together internally

for the +V Out; three other pins (4 to 6) are connected together internally for

the V Return.

12.3 Mating Interface Board. Figure 5b shows a mating interface board which

is available for simplifying the testing of a PCM/TPCM PowerCassette. As

shown in the photograph, provision is made for input and output connections,

and also for the control and monitoring signals.

12.4 Output Voltage. The output voltage is factory set to its nominal value to an

accuracy of ±1%. The voltage can be more accurately adjusted to a value

within a ±5% range by means of external components as shown in Figure 6.

12.5 Output Power. The maximum continuous output power is 650 watts for the

12V output, 700 watts for the 24V output, and 800 watts for the 48V output.

For the front IEC input versions (Option E) the output power is 480, 525 and

600 watts, respectively. The 5V standby output produces 1.25 watts.

The maximum output power of a PowerCassette may be drawn up to 50

ambient temperature. Above 50

C the total output power must be derated by

2.5%/

C. See Figure 7. The maximum operating ambient temperature is

C, at which the total output power must be derated by 50%.

12.6 Output Overload Protection. The PowerCassette output is protected from
