Subject: New -48 vdc, 800 amp rectifier emersen network power
We have ( 20 ) of these Lorain RHM800E50 rectifiers and ( 10 ) DC Static Power Plants each rated for 10,000 amps ( 6 ) distribution bays with sixteen 400 amp telco disconnects in each and ( 4 ) with twenty four 400 amp telco disconnects in each, all with full metering, fuses, overhead bus kits and ( 8 ) 1,200 amp bolted pressure switches to feed the battery plant 68,000 total distribution amps 100,000 amps in all of NEW! high quality network power plant.
The Lorain RHM800E50 800 amp model, provides regulated power and high operating efficiencies in a -48 volt system. Performance is assured with Network power produced transformers, gold printed circuit board contacts to resist oxidation and specially rated capacitors that last four times longer than standard capacitors.
These units have full metering with + 2% output voltmeter and ammeter for monitoring rectifier operation. One set of contacts for rectifier failure alarms and signals for end cell switch inhibit, high voltage alarm shutdown alarm and low current alarms.
External battery eliminator filter:
Reduces noise to less than 32dBrnC with resistive load. the filters is 5.22" (13.26cm) high x 15" (38.1 cm) deep.
Selective high voltage shutdown
Phase Shifting Remote rectifier On/Off Control
Output Voltage Float - 48.0 - 54.0 VDC Equalize - 48.0 - 57.0 VDC
Regulation Steady-state +S% from no load to full load over the specified input voltage, frequency, and ambient temperature ranges
Dynamic Response ( on battery ) Maximum voltage transient will not exceed +5% of initial steady-state voltage for step load change of 250 amps within range of 5% to 100% of full load. Recovery to steady-state voltage regulation range does not exceed 200 ms and all transient behavior disappears within 500 ms.
Filtering Voice band noise is less than 32dBrnC on batteries rated in amp-hours at four times the rated charger current. Wide band noise is less than 500 mv peak over the frequency range of 10 Hz to 14 MHz when measured on battery rated in amp-hours four times the rectifier output current. Audible noise is less than 65dBA at any point 5' (1.52m) from any vertical surface.
Current Limit adjustable from 90% to 125% of rated load.
High Voltage Shutdown circuit causes shutdown if output fuse ratings
Operating Temperature 0 to + 50 C ( +32 F to 185 F )
DC Output Volts / amps -48 / 800
AC input Volts/ Frequency Amps 480 / 60 Hz / 62.2
Dimensions: 84.25 inches high x 36 inches wide x 15 inches deep.
