LSAH / LSA 43.3 IC7 / LSPM water-jacketed low-voltage generators for cogeneration and embedded systems
Country: France · Model: LSAH / LSA 43.3 IC7 / LSPM
Water-jacketed generators of three lines, LSAH, LSA 43.3 L7 IC7 and LSPM, for cogeneration, compact soundproofed sets and variable-speed systems. LSAH covers 10–94 kVA, LSA 43.3 L7 IC7 gives 70 kVA at 50 Hz, and LSPM develops 2500–8250 Nm. Machine heat goes into the coolant circuit and then into the plant's heat scheme.

Description
LSAH 42.3 delivers 10–33 kVA at 50 Hz (400 V) and 12.5–41 kVA at 60 Hz (480 V), noise 82.2 dBA. LSAH 44.3 gives 40–75 kVA at 50 Hz and 50–94 kVA at 60 Hz, noise 81 dBA. Cooling is IC7A1W7, water flow 3–10 m³/h, coolant temperature up to 75 °C, ambient up to 80 °C, protection IP44 (IP55/IP56 optional). LSA 43.3 L7 IC7 is a two-pole enclosed 70 kVA, 50 Hz machine with an air/water heat exchanger, a mixed 2/3 and 5/6 winding and a digital D550 regulator. Power and signal circuits are brought out to Harting connectors, protection is IP 6K9K, ambient up to 80 °C, coolant up to 93 °C. LSPM is an eight-pole permanent magnet machine with IC71W cooling, voltage up to 690 V (star), insulation up to IVIC class C per IEC 60034-18-41, insulated bearings, a lubrication interval of over 1000 h and a permissible tilt of 15°/22.5°. All generators comply with IEC 60034, NEMA MG 1.32-33, ISO 8528-3, CSA C22.2 No. 100-14 and UL 1446, and are made under ISO 9001 and ISO 14001.
How to choose
Selection starts with the operating mode. For cogeneration with heat recovery take LSAH, for a compact 50 Hz 70 kVA set LSA 43.3 L7 IC7, for a converter drive with variable frequency LSPM. If you need more than 94 kVA, look at TAL 040 – TAL 049 for 10–1000 kVA or LSA 49.3 IC6 / IC8 for 435–800 kVA with a heat exchanger.

FAQ
What is the water jacket in LSAH for?
The liquid circuit removes heat from the generator and directs it into the heat scheme of the cogeneration plant. Coolant temperature is up to 75 °C, water flow 3–10 m³/h.
What power does LSA 43.3 L7 IC7 have?
70 kVA at 50 Hz, voltage 220–240 / 380–415 V. It is an enclosed two-pole machine with a digital D550 regulator.
What voltage and torque is LSPM designed for?
Voltage up to 690 V (star), torque 2500–8250 Nm. The machine works only with a power converter at variable speed.
What marking do these generators carry?
CE, UKCA and CMIM, and they can also be built into plants carrying CE marking. A marine certificate is possible for LSPM.
What is the voltage accuracy of LSAH?
±0.25% with AREP excitation and the D350 regulator, optionally D550. No-load THD is below 2%.
