P1399 ELECTRIC SERVO ACTUATOR (ESA) GEARCHANGE UNIT
The next generation of transmission actuation is ‘ratchetless’ electric drive. Xtrac have developed an ingenious approach that enables a small and light form to actuate the transmission quickly, accurately and repeatedly, whilst only drawing low electrical currents from the car system.
Specification
- Black anodised aluminium 2014 T6 housing
- CAN link for data transmission to vehicle
- Operating temperature range from 0°C to 80°C
- Environmental protection IP65
- 12-18V supply
- Current Draw 30A nominal during shifting
- 9 position with 40 degrees barrel rotation between shifts
- Internal potentiometer (0-5V analogue output)
- Each unit has its own unique serial number
- Deutsch Autosport AS012-35PN electric connector (22 pin)

Benefits
- Reduced overall vehicle weight due to no requirement for additional compressors, valve-blocks, batteries or capacitor packs
- Direct actuation results in faster shifting
- Internal Mechanical design inherently prevents ‘overthrows’ and ‘position drift’
- Direct barrel actuation reduces parts count within gearbox
- Gearshift can be controlled by ECU – Separate GCU is not required
- Lower servicing costs than conventional systems due to fewer components / assemblies
- Interchangeable mechanical interface with Xtrac IVA products (P1154 & P1254)
