4 channel 5A Power drive PM5

 

The PM5 can drive 5 digital/PWM outputs reaching as high current as 5A per channel, switching in range of 0-5/0-24 volts at a maximum frequency of 10KHz.

The PM5 is compatible with a single motor output of the GT1 at input end, while the output connector is compatible with the old standard DB9 port, so old astronomical mountings or motors are suitable for use.

The PM5 also is well insulated, using an optocoupler as input stage, can be over/lower volted safely.

It has these features and connectors:

  • RJ12 digital input connector, positive active
  • Coaxial supply voltage, center positive
  • DB9 output connector
  • High current and voltage: up to 5A/24V impulsive per channel
  • Optical input insulation

GoTo mount controller GT1

The GT1 is a stepper motor controller with goto functionality.

The GT1 can be configured to drive any kind of mount, since it is capable to adapt on any gear ratio from the configuration software.

You can change the gear ratio settings, microstep resolution, motor winding configuration and maximum goto/slew speed.

Each motor winding can be supplied by the GT1 with a maximum of 1 Ampere current.The GT1 supports overvoltage up to 18v for tight motor grip.

The GT1 is also compatible with the Skywatcher SynScan handset and EQMOD software, so you can use it standalone or by PC connection using software like SkyCharts, KStars or other software.It is also possible to drive the GT1 from the smartphone using INDI and KStars for Android.

The precision in low speed, including autoguide and sidereal tracking, is 64 microsteps.The maximum speed has no limit, but must be appropriate to the load and weight of the telescope and the power of the engines.The configuration software can set motor parameters, go-to acceleration and maximum speed.

It is equipped with these inputs/outputs:

  • SynScan Hand-set compatible input
  • Autoguider input
  • Stepper output
  • Right Ascension Stepper output
  • Declination Stepper output
  • 12v Power input
Being compatible with the Merlin protocol it can be connected directly to the computer and driven by software like EQMOD.
The precision in low speed, including autoguide and sidereal tracking, is 64 microsteps.

The maximum speed has no limit, but must be appropriate to the load and weight of the telescope and the power of the engines.

The configuration software – downloadable here – can set motor parameters, go-to acceleration and maximum speed.

The firmware is upgradable.
