Allen-Bradley 1444-TB-A

• Power boost up to 6 A 

• High overload current, no switch-off

• Wide-Range Input

• Robust mechanics and EMC

Description:

Input voltage AC100...120/200...240V (switchable), 47...63 Hz

(85...132V AC / 176...264V AC, 210...375V DC, 

see also“Output: Continuous Loading”)

Wide-Range Input: With the switch in the 230V position the power-supply unit operates at low and moderate loads (until 3 A) at any input voltage between 95 and 

264V AC (see ‘Output’ below).

Note: At DC input, always leave the switch in the 230V position

Input current < 2.6 A (switch in 115V position) 

< 1.4 A (switch in 230V position)

• DCin at open output typ. 5 mA (preserves battery sources)

Inrush current typ. 15 A at 264V AC and cold start

If you intend to protect the primary side of the power supply with a fuse or a circuit 

breaker, a 10 A slow acting fuse (HBC) or a supplementary protector 1492-

SPU1C100 is recommended. In order to meet local requirements, please consult local codes and regulations for proper installation.

EN 61000-3-2 (harmonic current emissions) is fulfilled
