Eagle power EP-40A HV 300-500V 70-120S ESC For UAV (A pair) Free Air Express Shipping (Global Warehouse)

1. Input voltage range  DC 300-500V, maximum input power supply voltage: DC500V, corresponding to the number of lithium battery cells: 70S-120S 

2. Working current:Continuous continuous working current 25A (good heat dissipation and ventilation conditions, and the case temperature is below 85°C) Peak current 40A (10 seconds) 

3. Control signal standard:1. Compatible with a model airplane remote control cycle of 50Hz, high level time 1000-2000us command, the highest input frequency can reach 400Hz. Note: The maximum input pulse width must be below 2050us. 2. The remote control input signal ground is isolated from the power supply ground, and the remote control signal is transmitted internally through optocoupler isolation. The red wire in the middle of the remote control line must be supplied with 5-8V power by the receiver or flight controller. 3. The throttle stroke can be calibrated, the same as the general ESC calibration method: before powering on, input the maximum value of the remote control signal, and then turn on the power, the ESC will emit a series of sounds, and when the sound stops, input the remote control signal At the minimum value, the ESC will emit a series of sounds. After the sound stops, disconnect the power supply and re-energize it. Detailed reference (description 7) content 

4. With 10 minutes no operation sound prompt to avoid forgetting to power off when not flying, some versions do not have this function 

5. RPM signal output with motor power cycle

ESC Electric The electrical timing of the ESC is set to 15° The protection mechanism of ESC:1. Power on low throttle detection 2. Over temperature protection: When the temperature of the ESC reaches 115 degrees, the ESC will automatically reduce the output power 3. Locked-rotor protection: When the motor or load is blocked, the ESC will automatically stop output 4. Loss of remote control signal protection: when the remote control signal is disconnected, the ESC will automatically stop output slowly without brake 5. Waterproof function: the existing all-metal version does not have IP67 waterproof design
