(1) General

This unit employs many features previously unavailable in an industrial power supply. It has

been designed to withstand the high levels of interference found in heavy industry.

The Evolution 40-3x360-520/24 has a high level of reserve power. This enables loads with

significant inrush current to be supported and will also ensure that circuit breakers will trip in

event of short circuit.

A protective feature is provided which will take control as the unit approaches the power limit

due the overload or excessive temperature brought about by lack of ventilation.

If input voltage drops down to 3 x 300 VAC for 4 sec, output voltage still complies to PLC

standard EN 61131-2 (≥ 20,4 VDC).

Use only in star-architecture networks.

(3) Features

[1] Output terminal:

Conductor sizes

Solid 2,5 - 16 mm² / 13 - 5 AWG

Stranded 2,5 - 16 mm² / 13 - 5 AWG

Stranded with ferrule without / with plastic sleeve 2,5 - 16 mm² / 13 - 5 AWG

Ferrule minimum lenght must be

≥ 10 mm

Wire insulation temperature rating 75°C

Tightening torque: min. 1,2 Nm / 11 lb. in.

[2] Bi-color LED, output voltage ”OK” – green, overload – red.

[3] Output voltage adjust 22 - 28 VDC;

when over 24 VDC is used, must input voltage be accordingly higher.

[4] Input terminal:

Conductor sizes

Solid 1,5 - 6 mm² / 15 - 9 AWG

Stranded 1,5 - 4 mm² / 15 - 11 AWG

Stranded with ferrule without / with plastic sleeve 1,5 - 4 mm² / 15 - 11 AWG

Ferrule minimum lenght must be

≥ 8mm

Wire insulation temperature rating 75°C

Tightening torque: min. 0,5 Nm / 7 lb. in.

(4) Location

The power supply is cooled by natural convection. Top and bottom clearances should be

50 mm at minimum. When used with maximum output power and high ambient

temperature (>50°C), front and side clearances shall be 100 mm minimum. The ambient

temperature should be measured on the underside of the unit. There will be an increase

of 25°C at the top. If natural convection is restricted, forced cooling should be used.

Mounting should comply with EN 60950-1 point 4.7 and 4.6.1. Protection class of the case

IP20 (EN 60529).

(5) Mounting [7]

The rail should be fixed solidly so that it cannot twist when mounting or removing the unit.

Mounting instructions [5], Removing instructions [6].

(6) Switching on

Factory set, ready to use, check the connection diagrams for parallel and series

connection. Check the connection diagram for DC use [13].

(7) Loading capacity

The nominal current is 40 A but due to the nature of industrial loading, the power supply

has been designed to support loads with high inrush currents without damage or

shutdown. Curve [8] shows the typical voltage / current curve. Decreasing part of the

curve [8] shows the current limitation. Curve [9] shows the typical overload / temperature

limit. To ensure correct convection cooling, the unit must always be mounted with rail

horizontally. Power supply is designed to give 150% output power (power boost) for min.

4 seconds [10].

(8) Parallel connection [11]

Up to 5 units may be connected in parallel. The open circuit voltage of each unit should be

set to same value. Accuracy of setting will determine how well the units share the load

current. The gauge and lenght of the cable between each power supply and the common

point should be the same.

(9) Series connection

Up to 2 units may be connected in series to give either 48 VDC or +/-24 VDC. Check the

connection diagram [12].

(10) Using circuit breakers on the power supply output:

On the short circuit, the power supply will trip, for example, the following ABB-STOTZ

circuit breaker:

S201-C6A

S201-Z16A
