Alpha 600 Series

Quesco is a leading innovator in the industrial sales market, particularly known for its advanced industrial radio remote control systems. One of their best-selling product is the Alpha 600 series which has significantly transformed the industry standards. The Alpha 600 series is praised for being waterproof and durable, promising longevity in even the most harsh industrial environments. As a testament to Quesco's commitment to innovation, the Alpha 600 series boasts super power-saving features, ensuring optimal and efficient operations.

Visualized Software


This series allows you to set every kind of function combination on the software setting display by connecting programmers and radio remote controls via a USB interface.


Adjustable PLL RF Module


Both transmitter and receiver are equipped with PLL (Phase Lock Loop) synthesized RF module with 68 sets

of user-selectable RI• channels (narrow band FM) for the transmitter code transmission.


Complete e Auto-Test System


Multi auto-test functions are available, including_: receiver and transmitter low voltage test, warning, auto shutdown, pushbutton breakdown test, main relay breakdown test... etc.


Super Power Saving


The receiver's MAIN relay is programmed to drop (open) the "Main Line Disconnect Contact" after several minutes of inactivity- The auto shutdown time can be selected on software setting display. The intermittent data transmitting is designed for power-saving purpose, so the fully charged batteries can be used for over consecutive 120 hours


Electromagnetic Induction Charge


The undisclosed metal and sensor type contact of the battery charger provides immediate charging simply by placing the transmitter into the charging slot.

Opening the battery cover to charge the battery is not needed. With this design, the transmitter's waterproof function and structure strength are increased. The transmitter's operating life is also prolonged.

Available charging source voltage : 100 ~240 VAC.


Shock Absorbing Rubbers are available for transmitters

The shock-absorbing rubbers on the transmitter top and bottom strengthen the shock-absorbing ability and frequent dropping.


Waterproof and Durable

The transmitter and receiver enclosures are constructed from high grade composite materials that resist cracking and deformation commonly occurring from frequent drops and long-term exposure to heat, sunlight, and harsh environments. The enclosures are fully sealed and impervious to dust and
