Note: The Kendrick Premier Controller will be available in the fall.

Astro-Physics is pleased to offer the Kendrick Premier Power Controller Package. This is the most advanced controller of its type. The controller shown in the images here is called the "Observatory" version. Unlike the standard version, it has no display.

There are two versions of it (both remotely controllable). One has a touch screen and another (known as the Observatory version) without any screen at all, designed strictly for remote control. A remote control web app is also underdevelopment and is looking very nice!

Both version (Observatory and Display) can be operated remotely, using either:

1. USB to PC for local remote control.
2. Bluetooth to Android devices for local remote control.
3. RJ11 (using RS-485 communication protocol) for long distance remote control.

Here are some of the new controller specs (specs may change without notice):

• 3.5" touch screen, (resolution 320 by 240).
• An Observatory version of the controller without a touch screen and designed for users with dedicated remote control observatories.
• 2.5mm Audio Jacks for optic sensors.
• USB-A port for External ambient and humidity sensor (various cable lengths to suit your needs).
• USB-B remote control port for short distance communication.
• RJ11 port for remote control port for long distance communication (over a kilometer possible).
• RJ11 port for connection and remote control of peripheral devices.
• Bluetooth capable. Android app under development
• Remote control via a web browser. Web app and tiny remote web server under development.
• New optic sensor design.
• Operating voltage 12 to 28 vdc.
• Upgradeable firmware via the internet.
• 3 dedicated 12 volt power ports to power peripheral devices (2 are probramable down to 8 vdc for powering DSLR cameras).
• LEDs on the heater ports.
• LEDs on the programable power ports. (LED will come on when that particular port is programed at 8 volts DC to differentiate it from a 12 volt port)
• ON/OFF switch

The feature functions that are built into the firmware are:

• Temperature sensing.
• Humidity/Dewpoint sensing.
• Optic temperature above ambient temperature control.
• Dewpoint control.
• Fixed temperature control.
• Power to heater % control.
• Choose Celsius or Fahrenheit screen display.
• Screen brightness control.
• Night Mode red screen.
• Low voltage cut-off. For those who do not want Low Voltage Cut-off, this function can be disabled via the display screen and/or the remote control software.
• Battery voltage display.
• Air temperature, Optic Temperature, Humidity and Dewpoint display.

This controller replaces the original, long standing Model VI controller. The Standard Dual Channel has a ton of new features but is really simple to use! As well, it can handle more power and use that power more efficiently!

Features & Specifications:

• Rugged Plastic Case with modern styling.
• Zero to 100% heater control.
• Fused onboard. Auto Reset.
• On board protection from over current, over temperature, over voltage.
• LED overcurrent indication at both outputs.
• 10 amp capacity (5 amps per channel).
• 6' detachable fused Power cord. Cord is fused at 7 amps.
• Reverse polarity protected.
• On/off switch (no other dew controller on the market has this).
• RFI (radio frequency interference) free. A critical feature for astro imagers!
• Pulse Width Modulation duty cycle control.
• 4 outputs, 2 for each control knob.
• LED Power on indicator for both outputs.
• Low voltage cut-off control with LED indication (a Kendrick standard!). IMPORTANT NOTE on this feature.
• Mosfet transistors built on board and on EACH output (no voltage drops!). Get the best possible performance out of your heaters!
• Velcro attachment. Parts included.
• 12 VDC operation.
• Dimensions: 4" x 3" x 1.35" (1.75" with knobs).
• 1 Year warranty

Standard Dual Channel Controller Manual (PDF)

The Micro Controller is designed for Astronomers and Astrophotographers who want the best in lightweight, compact, Grab'n'Go gear.

Despite its small size, this controller is not small in its performance or build quality. It is well built and well thought out.

The controller has two slotted tabs that can be used to attach the supplied lanyard so that the controller may be hung from a convenient location. Velcro tabs are also provided if you prefer to "stick" the controller to your telescope or mount. Also, the mounting tabs are convenient for anyone who wants to mechanically mount the controller with screws to a Dobsonian telescope base, Dobsonian upper tube assembly, inside an eyepiece box or wherever else one may wish to mount the controller.

TECH SPECS for the Micro-D Controller:

• ELECTRICAL SPECS: 12 VDC, 3 amps.
• Single channel, one RCA output for heater attachment.
• One output at 8 vdc for powering a DSLR camera. Connector is a 5.5mm x 2.5mm DC Power Jack. Requires the purchase of one of our DSLR power Couplers (Canon & Nikon cameras)
• Simple rotary knob control.
• LED Power status indication.
• Low voltage cut-off control. (a Kendrick standard!). IMPORTANT NOTE on this feature.
• RFI Clean. A must for CCD imagers!
• Pulse Width Modulation duty cycle control.
• Reverse polarity protected (a Kendrick standard!).
• Fused on board with Auto Reset. (the provided power cord is fused as well at 7 amps)
• Mating Terminal Block power input. This will allow users to terminate the controller power cable in a connector of their choice.
• Fused power cable included (cigarette lighter plug).
• Weight: 1.6 oz (30 grams)
• Dimensions (excluding tabs): 65mm x 36mm x 25mm (2.56" x 1.4" x 1.0")
  (including tabs): 80mm x 36mm x 25mm (3.15" x 1.4" x 1.0")

IMPORTANT NOTE: Micro-D Controller is designed as "light-duty". It is very compact and light weight...perfect for "grab & go" using small batteries. It is NOT designed to run large heaters. Suitable applications include:

• Small refractors up to 4" diameter
• Camera lenses
• Eyepiece heaters
