Honeywell 621-9933C I/O rack power supply 115/230 Vac 15 amps

Description

The 621-9933 I/0 Power Supply provides power for modules within the I/0 rack. It is a double width module and may be used only in an I/0 rack. The modules's front panel contains terminals labeled with A (Line or Ll), B (common or L2) and a ground symbol for connecting AC power wiring.

The 621-9933 provides 10 to 15 amps of +5VDC for the I/0 logic circuitry in the rack. It also supplies 1.3 to 2 amps of ±15VDC. Figure 4 shows the relationship between current loads of the ±15VDC source and the ±5VDC source. If, for example, the ±15VDC source requires 2 amps, the ±5VDC can draw a maximum of 10 amps. If the ±15VDC requires 1.3 amps, the ±5VDC can draw a maximum of 15 amps.

The maximum power consumption of the 621- 9933 Power Supply is 110V A. A cold start of this power supply will require a maximum of 20 amps for one cycle. 

The input is selectable for 115 or 230V AC by the position of a toggle switch located under the component cover of the power supply. The 115V AC selection will allow a voltage range of 85 to 132V A C. The 230VAC allows 170 to 250VAC operation. The frequency for both ranges is 47 to 63 Hz. This power supply module offers a front-accessible fuse holder. It is shipped with a 4.0A Slo-Blo fuse installed for 115V AC operation. The 230V AC 2.0A Slo-Blo fuse is also shipped with the module. One green LED, labeled 5VDC, is energized when the 5VDC power is present.
