18 WM, 60°C

• Input: AC 230V

• Output: 24-28V / 480W (600W)

• 91% efficiency

• Ideal for parallel operation

• Simple fusing

Data sheet

Input

Input voltage AC 230V, +15%, – 20%

Rated Tolerances

• Continuous operation

• Short term (1 min) at 24 V/20 A

Input current 5A

Inrush current typ. 33A at AC 264V

Inrush current limiting done with a fixed 15R resistor (not a thermistor) which is bridged after the unit is running, so losses are minimised. That means no reset time even at a warm-start.

Fuse loading <10A

Unit is internally fused (fuse not accessible). For external fusing of unit and for input line protection, use circuit breaker with B-characteristic 10A or slower action, or alternatively T10A HBC fuse.

Parallel operation Yes, up to ten SL20 units

To achieve current sharing the output V/I characteristic can be altered to be 'softer' (25V at 0.4A, 24V at 20A). This is done by repositioning a bridge connection (without opening the unit).

Housing dimensions and Weight

• W x H x D

• Free space for ventilation

•Weight

Design advantages:

• All connection blocks are easy to reach as mounted at the front panel.

• PVC insulated cable can be used for all connections, as the connection blocks are mounted in the cooler area on the underside of the unit.

Electronic current limiting, protects against overload and short circuit:

•V

out

Advantages of the switch-on/overload behaviour:

• Safer switch-on into highly non-linear loads with large starting currents

• Short-term overloads result in current limiting and not in an immediate shut-down.

• Parallel operation of several units possible. Proper switch-on performance is obtained.
