Description
LSAP 40 is made single-phase for 3.5–15 kVA or three-phase for 5–20 kVA, and LSAP 42.3 single-phase for 20–40 kVA or three-phase for 25–63 kVA. Next come LSAP 44.3 (70–160 kVA), LSAP 45 (180–320 kVA), LSA 47.2 (380–625 kVA), LSA 49.1 (660–1010 kVA) and LSA 50.2 (1250–1650 kVA). Insulation is class H, winding pitch 2/3, protection IP23, installation altitude up to 1000 m, permissible overspeed 120% for 2 minutes. Cooling air flow grows from 0.06 m³/s in LSAP 40 to 1.8 m³/s in LSA 50.2. SHUNT excitation is fitted with analog regulators R120, R150 or R250, AREP excitation with regulators R438 or R450, and the digital D510C is offered as an option. Steady-state voltage is held within ±0.5%. Anti-condensation heaters, bearing (BTD) and winding (RTD) temperature sensors, and current transformers for droop and measurement are available as options. For the frame sizes there are catalogs, DXF/PDF drawings and operating manuals for LSAP 40–46.2, LSAP 45 and LSAP 47.
How to choose
Selection starts with power and number of phases. Single-phase loads up to 40 kVA are covered by LSAP 40 and LSAP 42.3, and for three-phase sets from 70 kVA take LSAP 44.3 and the larger frame sizes. If you need an enclosed version with a heat exchanger for 435–800 kVA, look at LSA 49.3 IC6 / IC8. For the four-pole LSA 40 – LSA 47.3 range of 10–660 kVA with efficiency up to 96.9%, the separate LSA 40 – LSA 47.3 item will fit.

FAQ
What power range does the LSAP range cover?
From 3.5 kVA in the single-phase LSAP 40 to 1650 kVA in LSA 50.2. Single-phase versions exist only in LSAP 40 and LSAP 42.3; larger frame sizes have a three-phase winding.
What protection and insulation class does the generator have?
IP23 protection and class H insulation with a winding pitch of 2/3. Installation altitude up to 1000 m.
Which voltage regulators are fitted to LSAP?
With SHUNT excitation these are the analog R120, R150 or R250, with AREP the regulators R438 or R450. The digital D510C is offered as an option.
What short-circuit current does a generator with AREP withstand?
300% of rated for 10 s. This time is enough for the protection to trip the faulty line.
How many leads and what harmonic level does LSAP have?
Single-phase versions have 2 or 4 leads, three-phase 6 or 12. Total harmonic distortion ranges from below 1.5% in LSA 47.2 to below 5% in the single-phase LSAP 40, and the NEMA telephone influence factor TIF is below 50–100.
