fj45 rada

Description

Multipurpose power-supply/charger (thereinafter power-supply) Fj45 12V/24A, 24V/15A a 48V/8A is designated for an installation in a cabinet or another purpose-built appliance that works with or without station battery connected. They are designated mainly for automatic operating charging.

The mechanical configuration allows built-in mounting into distributors on both horizontal and vertical panels as well as DIN rails. The operation position is vertical.

Signalling of the operation status is provided by the LEDs:

  • green – AC mains OK
  • yellow – DC current
  • red – failure - signalling of the failure – reduction or elevation of the DC voltage

The Fj45 power-supply is equipped with the overvoltage protection that switches the power-supply off and signalizes the failure at dangerous elevation of the output voltage.

Stabilized voltage is temperature- compensated using an external sensor. If there is no sensor connected, the setup corresponds to an ambient temperature of 25°C. The power-supply has a natural cooling without the forced air circulation.

Special setting

When specially set to 1.44V/cell, it is also suitable for charging of NiCd batteries as well as gel-type batteries. The charging goes on according to the IU type charging characteristic.

Setting of the output voltage

 The power-supply allows fine regulation ±1% of the output voltage using a regulation screw on the front panel. To increase the output current or voltage the Fj45 power-supplies allow both parallel and serial operation.

The power-supply can be ordered with an increased dielectric strength 4kV and it is certified for using in applications in Czech railways (ČD, a.s.).

The charger FJ45 DS - with remote signalling

fj45dskontakty m

The power-supply Fj45 DS is equipped with a remote signalling connected to CAN9 plug on the front panel. There are two free-potential contacts 24V/100mA. One contact watches overvoltage the other one undervoltage. Both voltage levels can be set including hysteresis for each contact.
