ABB SD833 Ability ™ System 800xA ® hardware selector

ABB SD833 Ability ™  System 800xA ®  hardware selector

The SD83x Power Supply Units are designed to meet all the applicable electrical safety data stated by the EN 50178 harmonized European Standard Publication and the additional safety and function data required by EN 61131-2 and UL 508.

The secondary output circuitry is accepted for SELV or PELV applications. They are switch-mode Power Supply Units that convert the mains voltage to 24 volts d.c. These power supplies can be utilized for non-redundant and redundant applications.

Redundant applications require diode voting units SS823 or SS832. With the type SD83x series Power Supply Units, there is no requirement for the installation of a mains filter. They provide a soft start feature;  power-on of an SD83x will not trip fuses or earthfault circuit breakers.

Features and benefits

Simple DIN-rail mounting

Class I Equipment, (when connected to Protective Earth, (PE))

Over-voltage Category III for connection to primary main TN network

Protective separation of secondary circuit from primary circuit Accepted for SELV and PELV applications

The output of the units is protected against over current (current limit) and over voltage (OVP)

Basic information and parameters

The product number is 3BSC610066R1, the type is power supply, the rated output current is 10A, the rated output power is 240W, the rated output voltage is 24V DC, and the rated input power is 447/514VA.

Mains/Input voltage rating is 100-120V AC, 200-240V AC, with automatic input selection. The allowed mains voltage variation is 100-120V AC ± 10%, 200-240V AC ± 10%, and mains frequency is 50-60Hz ± 6%.

At startup, the primary peak surge current is less than 10A, there is no load sharing function, no monitoring relay, the power factor at rated output power is 0.59/0.51, and the heat dissipation is 24/22W.

When the maximum current is reached, the output voltage is regulated to<70mV/<100mV, the ripple (peak to peak) is<50mV, and the secondary voltage is maintained for 46/47ms when the main power is turned off.

When the ambient temperature is less than 45 ° C, the maximum output current is 12A, and the maximum ambient temperature is 55 ° C. It is recommended to use an external fuse with a primary rating of 10-20A and a secondary short-circuit current of 14-18A. The output overvoltage protection should be less than 39V.
