Channel A Fault Clip Fault Clip Operating mode Signal Operating mode Signal Channel C Fault Clip Operating mode Signal - DIGIPOWER POWER AMPLIFIER Full power even at 24 V DC single supply! An absolute must for system designs conforming to international standards. Power supply equipment according to EN 54-4 provides after a breakdown replacement power directly from the connected accumulator (24 V DC). Therefore power amplifiers must be capable to provide even at 24 V DC the full output power. The new ITEC DigiPower series not only meets this requirement, but offers also many other important features such as an “energy-optimized „stand-by” mode. 2 models: 2x250 W/100 V and 4x150 W/100 V Control LEDs for all signal and operation states Fault signals for battery and mains Fault signal for the power amplifier 2/4 channel in a 2 HU 19“ rack Low installation depth (only 260 mm) All connections plug-in/screw terminals Balanced inputs with transformer option Automatic stand-by mode Protection for open-circuit, shorts, over temperature, DC 230 V AC and DC 24 V power supply Start-up delay Maintenance-free cooling system without fans Digital signal processing Only 10 W power consumption in stand-by mode 24V DC 230V AC Channel B Channel D Fault Clip Operating mode Signal 16 DIGI POWER 4x150T
- BACKUP POWER SUPPLY (CERTIFIED ACC. TO EN 54-4) Backup power supply for system designs according to EN 833-4 and TRVB S 158 The digital power supply ITEC DSV54-4 is certified according to EN 54-4:1997 + A2: 2006. It is used to supply the components of the individual modules and for charging / monitoring of the emergency batteries. The power supply is intended for a connection to a 230 V/50 Hz (±15 %) power network and has to be connected via a two-pole pre-fuse of maximum 16 A. The integrated power supply provides power up to 300 W at 24 V DC. Thus during mains operation, in addition to the load current that is needed to recharge the batteries within 24 hours on at least 80 % of its rated capacity, sufficient power for the supply of 24 V system components (Spider44, SpiderMike2, Switch4 /1) is available (e.g.: 6 A for charging batteries with 160 Ah total capacity and 6 A for other devices). Supply voltage, connected batteries and the pre-fuses of the lowvoltage outlets are monitored by the ITEC DSV54-4. Errors are reported via LEDs on the front side and via potential-free relay changeover contacts. The internal resistance of the batteries is also measured cyclical. In case the resistance gets greater than 20 mΩ, it is reported at the front side via LEDs and relay contacts. The device is equipped with a deep discharge protection, which is activated when the battery voltage drops below 1.8 V/cell and which ensures a reliable protection of the batteries. 17
