Description
Two new core lengths for 700 and 750 kVA with an optimized power density have been added to the series. It has a rotating-field design, CoreCooling with an intense air flow through the active part, a wire stator winding with a 2/3 pitch, class H and IP23 protection. The AS440 with self-excitation is fitted as standard, and the options are the MX321 and MX341 with PMG, versions without an AVR, UL regulators and the digital VITA 05 with three-phase sensing. The versions are S5L1D (Dedicated), S5L1S (Special) and S5L1M (Marine), with adaptor feet for changing over between the S5 and S6 and flexible feet for replacing generators of other makes. Options include an anti-condensation heater in the terminal box, temperature sensors on each bearing, drip-proof louvers, a loss-of-excitation module and three-phase winding reconnection.
How to choose
For 400 V and 50 Hz the Dedicated range is 500–750 kVA. If less is needed, see the S4 (260–450 kVA); if more, the S6. The core length is selected for the output, and the new 700 and 750 kVA cover the top of the range. For marine diesel generators there is the S5L1M.
