www.pulsar.pl EN54-3A28 RED POWER 6.4. Technical outputs. The PSU is equipped with galvanically isolated indication outputs changing status after a specified event: • EPS FLT – output indicating AC power loss. The output indicates 230V AC power loss. Under normal status – with the 230V AC supply on, the output is closed. In case of power failure, the PSU will switch the output into the open position after a time lag determined in the „EPS” configuration menu (see section 6.3.3, Table 10).
www.pulsar.pl EN54-3A28 RED POWER The connection of external devices to the EXT IN input is shown in the electrical diagram below. OC outputs (open collector) or relay outputs can be used as the source of the signal. Fig. 12. Examples of connections. In the option with external switch, the V EXT jumper, which polarises the EXT IN input circuit and is required in such configuration, must be on.
www.pulsar.pl EN54-3A28 RED POWER 6.7. Increasing the number of outputs with optional EN54-LB4 or EN54-LB8 fuse modules. The PSU has two independently protected outputs for connecting the AUX1 and AUX2 receivers. If the power supply unit is connected with more receivers, then it is recommended to secure each of them with independent fuse.
www.pulsar.pl EN54-3A28 RED POWER 6.9. PSU overload. The PSU is fitted with the LED OVL (overload) on the PCB and indicator on the LED panel, informing about output overload. If the nominal current of the PSU is exceeded, the led turns on and the microprocessor starts a specially implemented procedure. Depending on time and overload level, microprocessor may disconnect the AUX1 and AUX2 outputs and switch into the battery-assisted operation. Restart will occur after 1 minute.
www.pulsar.pl EN54-3A28 RED POWER 7. Reserve power supply circuit. The PSU is fitted with intelligent circuits: battery charging circuit with the function of the accelerated charging and battery control, which main task is to monitor the condition of the batteries and the connections in the circuit. If the controller detects a power failure in the battery circuit, appropriate indication and activation of the APS FLT and ALARM technical outputs takes place. 7.1. Battery detection.
www.pulsar.pl EN54-3A28 RED POWER 7.6. Measurement of the resistance of the battery circuit. The PSU is checking the resistance in the battery circuit. During the measurement, the PSU driver takes into account the key parameters in the circuit, and once the limit value of 300m ohms is exceeded, a failure is indicated . A failure may indicate considerable wear or loose cables connecting the batteries. 7.7. Battery temperature measurement.
www.pulsar.pl EN54-3A28 RED POWER 8. Remote monitoring (options: Wi-Fi, Ethernet, RS485, USB). The PSU has been adjusted to operate in a system that requires a remote control of the parameters in a monitoring centre. Transmitting data concerning PSU status is possible due to an additional, external communication module responsible for communication in Wi-Fi, Ethernet or RS485 standard. The USB –TTL interface enables the connection between the PSU and the computer.
www.pulsar.pl EN54-3A28 RED POWER The RS485-WiFi „INTRE” interface is a device used to convert signals between the RS485 bus and the WiFi network. For proper operation, the unit requires an external power supply in the range of 10÷30V DC e.g. drawn from a PSU of the EN54 series. The unit is mounted in a hermetic enclosure protecting against adverse environmental conditions. Fig. 17. Ethernet network communication using the RS485 „INTRE” interface. 8.3.

www.pulsar.pl EN54-3A28 RED POWER The RS485-WiFi „INTRW” interface is a device used to convert signals between the RS485 bus and the WiFi network. For proper operation, the unit requires an external power supply in the range of 10÷30V DC e.g. drawn from a PSU of the EN54 series. The physical connection of the interface takes place under galvanic isolation. The unit is mounted in a hermetic enclosure protecting against adverse environmental conditions. Fig. 19.
www.pulsar.pl EN54-3A28 RED POWER 8.5. „PowerSecurity” program. The ”Power Security” program is available on www.pulsar.pl Its detailed description can be found in the manual. „Power Security” is a free computer program developed to view and analyze the information sent from the PSU installation spots. The main panel is presented below. Fig. 21. „Power security” main panel. It is possible to divide the main panel of the program into smaller areas, depending on the number of monitored power supplies.
