Overview

The 1-phase/2-phase power supply from the SITOP modular product line is a powerful,
stabilized technology power supply for automated machines and systems.

The key benefits of the product include:

● Wide-range input, which allows it to be connected to almost any 1-phase/2-phase line
supply around the world

● Output voltage can be adjusted in the range 24 - 28.8 V

● Power boost during operation with 300% rated current for 25 ms

● No lateral mounting clearances are required

● Ambient temperature -25 (0) … 70 °C

● Selectable short-circuit response (constant current or latching shutdown)

● A soft characteristic can be selected for a parallel connection (for uniform load distribution

of power supply units of the same type)

● Display of the operating state via 3 LEDs

● To increase the system availability, these reliable power supplies can be expanded using

SITOP supplementary modules (redundancy module, selectivity module, buffer module,
signaling module or signaling contact), as well as SITOP DC-UPS modules.

WARNING

WARNING

When operating electrical devices, it is inevitable that certain components will carry
dangerous voltages.

Therefore, failure to handle the units properly can result in death or serious physical injury
as well as extensive property damage.

Only appropriately qualified personnel may work on or in the vicinity of this equipment.

Perfect, safe, and reliable operation of this equipment is dependent on proper
transportation, storage, installation and mounting.

Before installation or maintenance work can begin, the system's main switch must be
switched off and measures taken to prevent it being switched on again.

If this instruction is not observed, touching live parts can result in death or serious injury.

The devices comply with ATEX directive 2014/34/EU; EN 60079-0; EN 60079-15.

SITOP modular is a primary-clocked power supply for connection to a 1-phase/2-phase AC
line supply. An electronically regulated DC voltage that can be set via a potentiometer is
available at the output of the device. The output of the device is isolated, no-load proof and
short-circuit proof. The LED displays indicate the operating state. The integrated signaling
contact (for 6EP1336-3BA00 and 6EP1337-3BA00, only when using the supplementary
6EP1961-3BA10 signaling module) can be used to further process the operating state of the
device.

Potentiometer

NOTICE

Thermal overload possible

Note

It is only permissible to use an insulated screwdriver when actuating the potentiometer.

2.3 Potentiometer

The potentiometer ③ on the front of the device is used to set the output voltage. The output
voltage is set to 24 V in the factory, and can be adjusted in the range 24 - 28.8 V; for
example, to compensate voltage drops across long supply lines to the connected load.

Figure 2-5 Potentiometer (example of 6EP1337-3BA00)

When adjusting the output voltage to > 24 V, the output current must be derated by 4 %/V,
or the permissible ambient temperature must be taken into account with 3 °C/V.

For notes on actuating the potentiometer (screwdriver, torque), see Figure 2-2 Terminal data
for 6EP1333-3BA10 and 6EP1334-3BA10 (Page 10), Figure 2-3 Terminal data for 6EP1336­3BA00 (Page 11) and Figure 2-4 Terminal data for 6EP1337-3BA00 (Page 11).

To switch the input voltage range for 6EP1336-3BA00 (24 V/20 A) and 6EP1337-3BA00
(24 V/40 A) to 120 V, a wire jumper must be connected to the input terminal, Jump 120 V

WARNING

Installing the device in a housing or a control cabinet

Mounting

Removing

The SITOP modular power supply is a built-in device. It must be installed in a housing or
control cabinet, to which only qualified personnel have access.

The device can be mounted in a control cabinet on standard mounting rails (see Chapter
Mechanical system (Page 49))

To mount the device, position it with the mounting rail guide at the upper edge of the
standard mounting rail and press down to lock it into place. If this is too difficult, press slider

① at the same time, as described under "Removal".

To remove, pull up the slider ① using a screwdriver ② and disengage the device at the
bottom edge of the standard mounting rail. Then you can remove the device from the upper
edge of the standard mounting rail.
