Pegasus Astro DSLR Buddy v2 Controller

Designed for the purpose of supplying DSLR cameras with constant power, the DSLR Buddy v2 from Pegasus Astro is a small device for astrophotographers that is also capable of powering a heater by shifting the duty cycle of the DC voltage (PWM control). Astro-imagers of all experience levels will find that this device certainly lives up to its name by being the ideal "buddy" to your DSLR in the mountains.

Enjoy guaranteed all-night camera operation with this dummy battery and integrated Dew Heater Output. The DSLRBuddy v2 is uniquely suited for time-lapse astrophotography applications (deep sky, star trails, etc).

Constant Power Supply for DSLR Cameras

Plug the dummy battery to your DSLR so you won't have to remember to replace the battery each time the power drains out.

Connect a 5-13.8V power supply to the DSLR Buddy to provide your camera with reliable, uninterrupted voltage for the entire night.

Either use the DC socket or the USB Micro socket. Use your Power Bank to step up voltage for your camera.

Automatic Voltage Selection

Without pause, the DSLRBuddy will automatically choose the highest voltage output whether DC IN or USB Micro socket.

Built-In Single Channel RCA Dew Heater Output

The DSLR Buddy has a built-in Pulse Width Modulation duty cycle control output for Dew Heater or Flatbox that provides more than 5A of current to your heaters.

Dew Heater output works only with DC 2.1 mm socket 5-12V input.

Simple Rotary Knob Control

By using the knob located on the side of the DSLR Buddy, you can manually dim the Dew Heater output. A red PWM duty cycle indicator light signifies the change in brightness when you make adjustments using this knob.

Reverse Polarity Protection

This device is designed to be protected from reverse voltage polarity. No worries if you accidentally reverse connect your power source.
