Table 3 - Operation specifications of the rectifier

Output regulation :	At the output terminals, the voltage is within ±0.5% of
	the set voltage value for all specified input and output
	variations, and within ±1% for any combination of
	specified input, output and ambient conditions.
Temperature drift :	Unless otherwise stated, all input and output
	parameters such as input voltage range, output current
	and voltage, current limit, etc. shall not vary more than
	2% over the operating temperature range.
Output noise and	• less than 22 dB of random noise on C band at voice
ripple :	frequency over the entire operating range of the
	rectifier, including operation in the current limit mode,
	and at low, nominal and high input voltage conditions
	( with or without batteries and measured at the point
	of regulation )
	• less than 20 mV RMS in any 3 kHz band between 10
	kHz and 20 MHz ( measurements made with or
	without batteries at the output terminals of the
	rectifier and with the rectifier in the local sensing
	mode )
	• less than 250 mV peak to peak switching voltage
	spikes ( measured differentially with an a 100 MHz
	oscilloscope )
Total harmonic	Less than 5%.
distortion ( THD ) :
Efficiency :	Better than 89% at a nominal input voltage of 350 V ac
	and for an output current ( load ) greater than 80 A.
Power factor :	Better than 99% with an output current ( load ) greater
	than 80 A.
Heat dissipation :	The maximum heat dissipation is 1420 watts
	( 4846 BTU / hr ) for an output current ( load ) of 200 A
	at –58 V dc ( when the ac input is 330-475 V )
Electromagnetic	The NT5C05CA / CB rectifiers when used in the
interference ( EMI ) :	rectifier cabinet NT6C43CA / CB ( equipped with the
	ac EMI filter kit NT6C18KB, or the NT5C05CC without
	external EMI filter ) meet the CISPR requirements for
	conducted and radiated EMI as specified in Publication
	22 for Class "A" equipment.
Reliability:	The rectifier has an MTBF greater than 120 000 hours
	under normal operating conditions, at 77°F ( 25°C ) as
	per Telcordia Technologies TR332 method.
