Aircraft Hydraulic Power Units LZH-M (N) - Cenzin

Aircraft Hydraulic Power Units
LZH/M & LZH/N
Airfield hydraulic power units are designed for:
checking the aircraft hydraulic system
filling the aircraft hydraulic system
purification of working fluid in aircraft hydraulic system
leakproofness checking of aircraft hydraulic system components in designated airport or airfield area
The units operate from 3-phase AC, TN-C or TN-S type supply network of:
rated voltage .............................................................. 3 x 230 /400 V
rated frequency .......................................................... 50 Hz
rated loading on one phase ........................................ 74 A
max. load on one phase ..............................................
150 A
power factor cos o| ..................................................... 0,8
Features:
The LZH/M can service many type of aircraft fitted with onboard hydraulic system of working pressure within the
3
range from 4 to 22 MPa and working fluid demand from 0 to 100 dm /min.
The LZH/N is designed for air transport by C-295M or other tactical transport aircraft.
Operating conditions:
The units can be used in open terrain under the following climatic conditions:
operating temperature range ............................ -20°C ÷ +55°C
max. relative humidity ....................................... 8% at temp. +25°C
