Curtis Controllers Model 1207B

The programmable motor speed controllers from Curtis Controller Model 1207B operate at a high frequency of 15 kHz, making them a noiseless and cost-efficient choice of controller for small-sized electric vehicles such as pallet trucks and sweepers among others. Controllers of this model have premium and high power features despite its compact and straightforward design. Similar to other Curtis con It is also compatible with the Curtis handheld programmer (Curtis 1311) and a PC application (Curtis 1314), which are optional mediums in adjusting parameters and conducting diagnostics and tests.


The Curtis Controllers Models under 1207B have a nominal voltage of 24 volts and a current limit range of 250-300 amperes. The controller only weighs 1.1 kg and is 165 mm in length, 122 mm in width, and 66 mm in depth. The design is one of the smaller ones from Curtis controllers, which is a key feature of the controller alongside it being a power MOSFET design. It also has well-protected components, cutback functions, and good control among others.


The Curtis 1207B controllers can now be purchased here in Cloud Electric, your one-stop shop for all your electric component needs. Cloud Electric is a leading distributor of electronic components in North America. We take pride in our informative product descriptions, pricing, and shipping speed.
