  • Page 6: Operation Principle

    Maximal current I for ZDSO400-DR2 is 6A, for PSU-24V-4 is 2x6A (two separated outputs 6A) – the value max a corresponds to the 6.3Amps fuses used. The listed range includes voltage values between the voltage of a discharged battery bank (at the end of the floating mode cycle) and the value of the bulk charging mode voltage, including temperature compensation.

  • Page 9 The circuit of the ZDSO400-DR2 or ZDSO400-DR4 power supply is equipped with a LVD – an internal switch of deep discharge implemented in the relays in their output circuits (one relay in each circuit for powering amplifiers and one at each double outputs for powering the VAS controller).

  • Page 10: Installation And Connection

    Fig. 6. Mounting the ferrite cores on the DC cables to the amplifiers The ZDSO400-DR2 power supply is equipped with two power supply outputs for VAS controllers, while the ZDSO400-DR4 power supply unit is equipped with four such outputs. If the VAS system requires a higher number of controllers and cooperating devices to be used, corresponding splitting should be implemented outside the power supply unit.

  • Page 11: First Start

    4. First Start 4.1. The initial information The first start of the VAS system including the ZDSO400-DR2 or ZDSO400-DR4 and connected batteries should be done by qualified service personnel of the Manufacturer or the properly trained authorized personnel.

The resistance measurements of the battery circuits are conducted periodically and on such the basis the battery configuration change can be detected.
  • Page 13 VAS modules. The voltage presence and its value should be checked by means of a voltmeter. In this state, the MAINS LED on the front panel of the ZDSO400-DR2 or ZDSO400-DR4 should be off and the FLT LED should be on.
