2223 DUAL SWITCHMODE POWER SUPPLY

• 24/115/230 VAC supply voltage

• 3.75 kVAC isolation

• 2 adjustable 5...24 VDC outputs

• Output: ± 5...24 VDC, 10...48 VDC

• Short circuit protection

• Thermal protection against overload

Applications:

Supply for small measuring systems that demand 2 stabilised voltages.

To achieve an adjustable output with minimum power loss, the 2223 is based on switchmode technology. The isolation test voltage between input and outputs being 3.75 kVAC, the unit is suitable in PELV/SELV circuits. The double-iso-lated safety transformer has a bimetal fuse that disconnects the input circuit if the internal temperature exceeds 100°C. The fuse automatically resets.

The 2223 is for standard 11-pole socket mounting in all positions. To achieve maximum cooling, vertical position and a small distance (10 mm) between neighbouring units are recommended.

Standard supply voltage according to the specifications. The built-in double-isolated safety transformer ensures galvanic isolation.

The outputs are adjustable by 2 front potentiometers in the ranges 5...24 VDC. Two green LEDs, Power on 1 and Power on 2, indicate active outputs. The short circuit pro-tection limits the current on each output. The two supplies are galvanically separated with 500 VAC test voltage and can be connected in series or used as two independent supplies with or without common gnd. By connecting the two outputs in series, 10...48 VDC or ± 5...24 VDC are achi-eved. The total output power must not exceed 7.5 W.
