Key to notations

BRAKE — electrical motor brake

• EMF brake for progressive braking in cars.
• Braking with motor short circuited ensures that folding propellers of electric
• gliders fold back reliably.

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

hec — High Efficiency Clock

• High motor pulse frequency
• Very fine control of motor speed
• Extremely economical on power under part-load conditions
• Longer operating times
• Reduced thermal load on motor at
• commutator/carbon brush junction

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

POR — Power On Reset

• Safety circuit — does not release the controller until the stick sin the “off

position

BEC — Battery Eliminator Circuit

• Receiver and servos powered from drive battery
• Only one power source in the model
• No separate receiver battery required
• Reduced weight
• Reduced space requirement

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

PCO - Power Cut-Off /low voltage monitor

• Enhanced safety for BEC systems in model aircraft
• Guarantees sufficient battery capacity for radio control system, when motor, the main power consumer, is switched off well before battery voltage drops to a dangerous level

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

TP — Thermal Protection

• Thermal overload protection

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

TOP — Thermal Overload Protection

• Double overload protection
• Super-fast current limiting
• Thermal protection

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

OPTO — Opto coupling

• galvanic separation effectively blocks interference produced by motor circuit.
