2.6.2.1. DPS-300AB-1A 337W redundant Main power module specification
General description :
This specification describes the performance characteristic of 337 watts Hot-swap
redundant power unit with +5V, +12V,+3.3V,-5V and –12V DC outputs.
Forced output current share : the SPS unit(DPS-300AB-1) is intended to work with cage
unit(RPS-600A) to form a redundant power module.
There are two configurations described as below :
(1) One single power supply operation,
It is configured as one cage unit ( Delta module name RPS-600A) compatible with one
power supply unit ( Delta model name DPS-300AB-1) for single power supply
operation
(2) Dual power supplies redundant operation,
It's configured with one cage unit ( RPS-600A) compatible with two units of power
supply (DPS-300AB-1) for dual power supply current sharing operation.
Under dual power supply redundant operation, the power supply's output current are
controlled electronically so that both power supplies share the loads.
Electrical Characteristics :
(1) Input voltage range: 90 Vac ~ 264 Vac, auto-range, single phase
(2) Input frequency range: 47 Hz to 63 Hz.
(3) Max. input AC current: 7 Amax. @ 115 Vac, 3.5A max. @ 230 Vac, full load
(4) Inrush current of this module shall not exceed 60 amperes peak at 100 vrms input
voltage, the inrush current measured at cold start.
(5) Efficiency: 63% min. At low line 110/220 VAC (60Hz) full load.
(6) Power Factor Correction : the power module (RPS-600A compatible with
