Electrical specifications of the Helios Rectifier 100/48

The electrical specifications of the Helios Rectifier 100/48 are listed in Table 25.

Table 25 Electrical specifications of the Helios Rectifier 100/48

Parameter	Specification
Input voltage:	208/240 V AC, 1-phase, 47-63 Hz
	Input voltage range: 176 to 264 V AC
Input current:	31 A nominal at 208 V AC input and -56 V DC, 100 A output
Recommended AC	50 A, two pole AC circuit breaker
service input:
Output voltage:	Float: -48 to -58 V DC
	Equalize: 0 to 4 V DC above Float
	Maximum: -59.5 V DC
Output current:	100 A per rectifier
	100 A for a one position shelf
	300 A for a three position shelf
Input protection:	A two pole / 45 A circuit breaker opens both lines.
Output protection:	The rectifier is protected by a 120 A circuit breaker at the output. The output current
	is limited to a value adjustable from 50% to 105% of the rated capacity of the
	rectifier. This circuit is factory set to 105 A.
Output regulation:	The rectifier output voltage is automatically regulated to remain within ±0.5% of the
	selected value under all load conditions and within the specified input voltage,
	frequency, and ambient temperature ranges. And within + 1% for any combinations
	of specified input, output and environmental conditions.
Efficiency:	Efficiency is better than 88% at a nominal input voltage of 208/240 V AC and an
	output load greater than 40 A.
Power factor:	Power factor is 0.99 at a nominal input voltage of 208 V AC and output loads greater
	than 40 A.
Electromagnetic	The rectifier meets the FCC requirements for conducted and radiated EMI for Class
interference (EMI):	“A” equipment.
Heat dissipation:	763 W (2606 Btu/hr)
