The proposed static or auxiliary converter shall be capable of charging the battery at a voltage range of 24 to 36 V at the mains voltage DC 600/750 V (adjustment depends on the auxiliary voltage level of the vehicle) and of supplying the auxiliary network at the maximum voltage setting, even under a permanent load of 200 A (expected useful maximum output power: 7,2kW). The housing should be designed with IP 65 housing. The battery is charged and the power supplied to the auxiliary network is supplied directly from the overhead contact line. The recommended model should ensure gentle and reliable charging of the battery with low current fluctuations (according to DIN 41773). It shall be possible to start the device without counter-voltage, the battery charger shall also operate in the case of a deep discharge battery (Blackstart function). The apparatus shall typically have the following characteristics: operating voltage range DC 400V to 900V automatically switch off when the mains voltage is DC < 400V or DC > 900V immediately switch back on if the input voltage has reached the allowed range inputs and outputs for the housing and body are free of voltage, electrical insulation requirements have a galvanically isolated output according to EN 50124-1 have full free-flow cooling, without moving parts cooling fan in the interior of the device can not be without battery (without battery counter-voltage), the converter must start without battery (without battery counter-voltage) as soon as the necessary input, overhead line voltage is available. with outputs with permanent short-circuit strength, it must be able to sustain the output current of the maximum DC output at the lowest input voltage and maximum allowed temperature DC output with a maximum pulsating current of 1% (peak-to-peak) and maximum voltage level fluctuation of ± 1%. the battery charging current can be parameterized, can be set, if the parameterization, adjustment is done via serial line, software (battery cell type (acid or alkaline), number of battery cells, etc.), parameterization software must be free of charge, for its use the bidder must hand over a training booklet (with which parameters we and how can be adjusted (electronically and printed in 1 copy) and 3 serial cables required for parameterization. The device must be suitable for charging both acidic and alkaline batteries, it must have a separate charging charger. The apparatus shall have an operating tell-tale output and the casing shall be of stainless steel or aluminium, painted or coloured. Dimensions of the space available for the installation of the auxiliary converter on the vehicle (the dimensions given may not be increased in either direction, otherwise the proposed unit will not fit in the space provided for this purpose on the vehicle): Length: 910mm o Width: 510mm o Height: 400mm More details can be found in the technical description! Total purchase (baseline quantity/corrective quantity) of the product specified in detail in the technical specifications included in the procurement documents: Up to 20 pieces. The contracting authority may deviate from the specified basic quantities by up to 4 pieces, i.e. by 20%, during the performance of the contract. Fixed frame: 20 pieces, optional frame: 4) During the term of the contract, the contracting authority undertakes to draw down a total of 20 basic quantities. Estimated value in terms of the basic total: net EUR 192.000 The name, brand name, etc. of the named type that may appear in the technical specifications were made in order to clearly define the nature of the product, in accordance with Article 321/2015. Pursuant to Section 46(3) of the Government Decree, contracting authorities shall accept products of an equivalent quality. When the product is delivered, the product documentation (parts list, wiring diagrams, measurement instructions for debugging, adjustment, instructions) shall be handed over, which is suitable for carrying out repair and maintenance tasks after the warranty period has expired. The Customer undertakes not to hand over this documentation to third parties. Documentation must be provided in Hungarian (both in digital form and on paper).
