BKE JSD-300-275/DIN2_CH_ODP DIN rail power supply/charger with 27.5 V, 300 W, 10 A, LAN port

Product detailed description

Product Description:

Industrial power supply/charger for Pb batteries on DIN rail BKE JSD-300-275/DIN2_CH_ODP 27,5 V, 300 W, 10 A, switched with battery disconnector to prevent deep discharge and damage. The power supply is equipped with remote management via SNMP or web interface allowing to manage the power supply and send alarms when the set parameters are exceeded. It is possible to remotely disconnect the output voltage for a short period of time to ensure the restart of connected devices. The power supply has protection against short circuit and overload at the output, overvoltage and undervoltage at the output and thermal protection. The charger is equipped with active power factor compensation (PFC). The power supply is suitable for powering information and telecommunication equipment with DC voltage backup. The power supply has an efficiency of more than 85%. The power supply can be operated without a battery connected.

Surveillance options:
Basic and clear monitoring of individual power supply parameters. The module provides information on the overall status of the power supply, the presence of the input network and the status of the protection
input, output and accumulator. The battery charging parameters - current voltage, current and temperature and the total current supplied by the power supply - are also monitored.
The ability to immediately determine the status of these parameters will allow technicians to discover the cause of problems in a given location before the actual trip.
Sources can report exceedances of monitored parameters by sending email messages. The threshold values of the monitored parameters can be user
can be set so that the module can warn the operator in time when an event occurs.

Parameters monitored:
- battery voltage
- status of the input network
- source status
- current to the battery
- battery temperature
- source current

Remote control:
- 10-second power supply output disconnect to restart powered technology
- possibility of sending e-mail alarms, traps
