MTA-70A-LV-OPTO( no bec) is a 70A brushless speed controller which can handle a maximum burst current of 90A . Specifically for Aircraft/ Gliders
Features:
- Easy setting, easy operation.
- Excellent Throttle Linearity and Response
- Separate voltage regulator IC for MCU which gives it high anti-interference properties
- Safe start-up system:
- The motor won't be started no matter which position the throttle stick is on when the battery is connected.
- Automatic power cut-off:
- When the motor stops rotating or the radio signal loses for more than 3 seconds, the power will automatically be cut off.
- High rate switching Pulse Width Modulation (PWM): 8KHz.
- Over-heat protection:
- The power will be cut-off as it is heated up to 110?.
- Over-voltage protection:
- The motor won't be started if the voltage is higher than 18V.
- Low-voltage cut-off:
- 3.0V/2.7V (selectable) for Li-ion/Li-polymer battery.
- 0.9V/0.7V (selectable) for Ni-CD/Ni-MH battery.
Timing mode:
- Timing low mode----providing highest efficiency suitable for motors with 2, 4, 6 poles.
- Timing high mode----providing highest rotation speed & biggest current suitable for motors with 6 or more poles and outrunning motors.
- Programming Card: AS to be used for setting ESC
- Programming can be done on the programming board easily.
Factory Default Setting:
- Brake off.
- Timing high
- For outrunning motors and motors with more than 6 poles.
- Throttle curve
- Linear.
Battery type
- Li-ion/Li-Polymer battery.
Cut-off voltage
- Cut-off voltage low. 2.7V for Li-xx battery.
Cut-off type
- Cut-off soft, reduce the power when voltage drops to the cut-off voltage.
90A Max Current Burst. No Bec need separate battery pack for receiver.
