Northern Lights Inc. has developed an option for 2-speed operation.
This allows the generator set to operate at a higher rotational speed to allow a 27% increase in PTO pump performance (power and speed).

This system is fully compatible with the standard control panels, TSC panels and S-3A autostart systems.
High speed operation is initiated by a customer supplied GEN/PTO mode selector switch.

The option includes an electronic governor system with overspeed protection at both electric generating speed and at the upper PTO speed.
The system includes a shipped loose AC output contactor that provides an interlock function that prevents generator AC output in the high speed mode.
The PTO can still be used with no change in operation at the genset rated speed.

This system is available for the following models:
M843LW3 rated 10 kw at 50 hz
M844DW3 rated 14 kw at 50 hz
M844LW3 rated 16 kw at 50 hz
M864W3 rated 20 kw at 50 hz
M944W3 rated 26 kw at 50 hz
M944T rated 32kw at 50 hz
M1064T1 rated 50 kw at 50 hz
