WARNING

Correct handling of the devices

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.

SITOP PSU8200 1ph is a primary-clocked power supply for connection to a 1-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 operating state of the device can be processed via the signaling contact. The device can be switched ON/OFF remotely using a remote contact.

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 2-3 Potentiometer (example: 6EP3334-8SB00-0AY0)

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.

The two switches A and B are used to influence the output characteristic curve:

influences the output characteristic in the load range

influences the output characteristic in the overload range

'Soft' characteristic curve (see, e.g. Figure 6-5 Output characteristic curve 6EP3333-8SB00-0AY0 parallel operation (Page 34)) for the parallel operation of two or more devices: The output voltage falls with increasing output current (namely, also for the overcurrent pulse!). This means that for full output current the highest

If the output current rises above the rated value and above the current limit, the device reduces the output voltage (see, e.g. Figure 6-7 Output characteristic curve 6EP3333-8SB00-0AY0 latching shutdown (Page 35)). If the output voltage falls below 20 V, the device shuts down latching, the red LED lights up. This limit voltage of 20 V is independent of the set output voltage. The 'Short-time overload current' feature is not available in this operating mode. Turning the power supply off for at least 60 seconds or a remote OFF and ON on the remote contact causes a reset (only with 6EP3333-8SB00-0AY0 and 6EP3334-8SB00-0AY0). To also guarantee the upload of large capacitances at the output in this operating mode, a non-latching shutdown is performed during the first 10 seconds after power on or remote ON. During these first ten seconds, the device responds for overload as if the
