Voltage Supervision and Power Supplies

In addition to fault annunciating and telecontrol technology, the EES product portfolio includes industrial electronic components, such as voltage supervision devices and supply voltage converters. All EES devices are distinguished by their compact design, high efficiency, and durable technology.

AC/DC POWER SUPPLIES

Wide-range switching power supplies, which are ideally suited as power supplies for telecontrol technology devices. Stable 24V DC output voltage is provided from the classic 230V AC supply voltage.

Широкообхватни захранващи модули, които са идеални за захранване за устройства за телеуправление или за анонсиране на неизправности.

BUFFER CHARGERS

Buffer chargers allow the safe and uninterruptible supply of the connected consumers with an accumulator buffering. An intelligent microprocessor based control ensures the optimal usage of the accumulator capacity and prevents an overload.

If a safe transmission of the last state in a facility in the event of a power failure is sufficient, buffered DC power supplies put themselves forward, based on ultracapacitors as energy storage. These ensure a maintenance-free operation of up to 30 years acc. to the ambient conditions.

The broad input voltage range from 115…230 V AC is being monitored for operation as well as the charging status by 2 potential isolated contacts and 3 LEDs.

  • – PLG-Buffer charger with Accu-backup
  • – CBS-Buffer charger with ultra capacitors
VOLTAGE SUPERVISION

The supervision relays are compactly designed and are suitable for mounting in the distribution cabinet.

The voltage supervision is carried out separately for every phase, so not only the mean average value of the voltages, but the actual asymmetry and the individual phase failure is being recognized. In addition the neutral conductor is also supervised on break. Limiting values can be adjusted through potentiometers.

The corresponding types are shown in the datasheet of the EUW-Series:
