Curtis Motor Controller Guide: PMC, SepEx and AC Models by Voltage and Current
Share
If you are holding a Curtis controller labelled 1268-5502 or 1207B-4101 and need to know what it is, what it replaces, or why the one you ordered will not drive the vehicle, this is the reference. Every model below is one we stock new — no remanufactured units, no core charges.
Step one: which family is it? This is the part you cannot change
The first four digits tell you the motor technology. A permanent-magnet controller will not run a SepEx motor, and neither will run an AC motor.
- PMC — 1204, 1205, 1206, 1207, 1209, 1214, 1215, 1219, 1221, 1229. Permanent-magnet DC. Two power leads to the motor.
- SX — 1243, 1244, 1266, 1268. SepEx, separately excited DC. Four leads: an armature pair plus a field pair the controller drives independently. That separate field is what gives you regen and electronic reverse without a direction contactor.
- AC — 1212, 1222, 1230, 1234, 1236, 1238, 1239 and the F-series. Three-phase induction or PMAC, with a motor speed or position sensor.
- 1510 and 1515. OEM upgrade controls for Club Car IQ and Excel platforms.
The quick field test: count the power studs on the motor. Two means PMC. Four means SepEx. Three phase leads plus a sensor connector means AC.
Step two: the throttle suffix, and what it actually means
Our listings carry a throttle note — (0-5V), (5K-0), (0-5K), (ITS), (3-Wire). This is the single most common reason a correctly rated controller will not move the vehicle, so it is worth understanding rather than guessing.
Curtis groups throttles into three types, and on the programmable models the type is a software setting you reach with a handset or PC kit, not a property of the hardware:
- Type 1, “5kΩ–0” — a two-wire resistive throttle. 5 kΩ at rest, falling toward 0 Ω at full speed. Curtis notes this is also the easiest type to use with a wigwag throttle.
- Type 2, “0–5V”, “0–10V”, 3-wire pot and electronic throttles — the controller reads a voltage. 0 V at rest, 5 V or 10 V at full speed. A 3-wire pot between 500 Ω and 10 kΩ works as a divider across the controller’s own current-limited 5 V supply.
- Type 3, “0–5kΩ” — the reverse of Type 1. 0 Ω at rest, rising to 5 kΩ at full speed.
ITS is the exception. It is the inductive throttle sensor fitted to E-Z-GO Medalist, TXT, DCS and PDS carts — a coil rather than a pot, with no wiper to wear out. An ITS-configured controller expects that sensor and its specific signal. It is not a pot type you can dial in, so match it at the point of order.
So the suffix in our listing tells you how a unit is configured as shipped. Types 1, 2 and 3 you can change yourself on a programmable model. ITS versus pot you cannot.
Step three: voltage and current
Voltage has to cover your pack. Current is the controller’s ceiling, not a target: a 500 A control on a vehicle that only ever pulls 300 A simply never reaches its limit, while a 275 A control where the motor wants 450 A gives you thermal cutback on every hill.

Programming
Most models above are programmable, and some arrive configured for an application that is not yours. Two tools cover the range:
- Curtis 1313K-3231 dealer handset — 4-pin Molex, handheld, no laptop needed. The usual choice for field work.
- Curtis 1314K-3301 PC software kit v4 — for saving and cloning configurations across a fleet.
Tell us the vehicle and what the controller is replacing and we will tell you whether it needs programming before it ships.
DC-DC converters for 12 V accessories
If you are adding lights, a radio or accessories to a 36 V or 48 V vehicle, use a converter rather than tapping one battery in the string. We stock the Curtis 1450 and Sevcon converter range, and this article explains why tapping a single battery fails.
Not sure which one you need?
Send us the controller’s full part number, the vehicle make, model and year, and a photo of the motor’s terminal block. Email matt@electricdrivesolutions.com or call (717) 421-9988 and you will reach an engineer, not a parts counter.
Everything we sell is new. See our Brand New Promise and warranty policy.
Throttle type definitions follow Curtis Instruments’ own 1207/1207A controller manual. Ratings are the manufacturer’s; confirm against the current datasheet for your exact part number before ordering.
