The two-way overspeed governor QUASAR from Dynatech for use in a shaft or elevator machine room is the smallest overspeed governor in the Dynatech portfolio. The QUASAR governor is suitable for detecting and preventing uncontrolled cabin movement (UCM). The governor is made in a design that prevents corrosion.
The QUASAR overspeed governor is produced in a minimalist design with a pulley with a diameter of only 120 mm and it can be used with ropes with diameters of 6 mm / 6.5 mm.
The overspeed governor includes an overspeed contact, protection against ropes falling out, a hardened groove and a safety switch with automatic reset (up to a nominal speed of 1 m/s inclusive).
The QUASAR SV overspeed governor can optionally be equipped with the following accessories:
- A3 coil for UCM, voltage 24VDC, 48VDC or 190VDC
- Coil for remote tripping (testing), voltage 24VDC, 48VDC or 190VDC
- Limiter cover (separate item, not included in governor packages)
- Test groove (not a standard part of the governor)
When using the governor together with the SD-BOX, the A3 coil voltage must be 24VDC.
The QUASAR soverspeed governor cannot be used for reverse mounting on the shaft ceiling, so-called "upside down".
