Schematic for parallel operation Instructions for parallel use a) Only SD834 can be used in parallel connection. b) Adjust the output voltages of all power supplies to approximately the same value (±500mV). Otherwise, the DC-OK signal might not work properly. c) A fuse (or diode) on the output is only required if more than three units are connected in parallel. d) Do not continuously load the terminals with more than 25A. Keep an installation clearance of 15mm (left/right) between two power supplies and avoid installing the power supplies on top of each other. Table 115. Power Supply Units - Fuses and Protective Devices Power Supply Units Types SD83x Fuse SD831 SD832 SD833 SD834 Primary: Recommended external fuse (1) min/max (1) Microcircuit Breaker (MCB), Characteristic B or a delayed action fuse. 10 - 20A 10 - 20A 10 - 20A 10 - 20A Primary: Recommended external fuse (2) min/max (2) Microcircuit Breaker (MCB), Characteristic C
SS822/SS823/SS832 Voting Unit (for Redundant Power Supply) The Voting Unit has been specifically designed to be employed as a control unit within a redundant power supply configuration. The output connections from two Power Supply Units, (PSUs), are connected to the Voting Unit. The Voting Unit separates the redundant PSUs, supervises the voltage supplied, and generates supervision signals to be connected to the computer system. Green LED’s, mounted on the front panel of the voting unit, provide a visual indication that the correct output voltage is being delivered. Simultaneously with the green LED illuminating, a voltage free contact closes the path to the corresponding “OK connector”. Voting Unit trip level’s, are factory preset. Three different types of voting units are available: SS822 up to 20 A. SS823 up to 20 A, with over voltage protections and enlarge diagnostics.
SS822 For SS822 Block diagram and Dimensions see Figure 99 and Figure 100. Table 118 and Table 119 shows the supervision data and the technical data respectively. For connection of SS822 in a redundant configuration see Figure 101.
