Hi,

Can you recommend a suitable power supply for TCM 110-42, which I can buy in the nordic countries?

We want a power supply which supplies voltages near the upper limit of 34V, and gives higher motor dynamics.

thanks

Standard power supplies typically provide 28V as nearest voltage. You might look for a laboratory supply, or cascade a dual supply with isolated outputs with 24V and 9V or similar.

We make our own power supplies.
Rating: 30V.
We can manufacture power supplies to any custom rating as well, including 34V for TMCM110.
30V supply is available from stock.

Specifications:

• Nominal power: 100W
  
• Regulated
  
• Method of conversion: analogue
  Low power dissipation. No EM interference.
  As opposed to Pulse Width Modulation (PWM) with its inherent strong electromagnetic interference.
  
• Overload protection (shutdown)
  
• Input and outputs are all galvanically isolated
  
• Input: 220V (other on request at no extra charge)
  
• Outputs:
  
  
  • 3A/30V (adjustable 24V-30V)
    
  • 0.25A/5V
    
  • Four lines - 5V, 0V, 24-30V, 0V - are available both externally and internally. Internal terminals are for a motor controller. External ones are duplicated for additional laboratory use, or for external motor controllers:
    
    • internal terminals: 4 capped loose wires;
      
    • external terminals:
      
      • 4x-array socket/plug pair with 1mm thin pins. The plug is 5.5x20.5mm in size, and has screw terminals for 4 wires.
        
      • 4 single sockets for plugs 4mm in diameter
  
  
• Load indication for each channel (30V, 5V): light emitting diode (LED)
  A LED switches off on overload (shutdown of the power supply).
  Each LED Can also be disconnected manually to save power.
  
• Ripple at max/min loads - better than:
  
  • 30V line: 0.4V/0.02V
    
  • 5V line: 0.2V/0.01V
  
  
• Internal cooler fan (can be disconnected at low loads).
  
• Conditions of use: indoors, laboratory.
  
• Casing: plastic, black. Other on request.
  
• Dimensions: box of about 18x16x9cm;
  a motor controller like TMCM303, combined with a BB303, or other device can be placed inside.

Certification: none (it is a small quantity custom production)
Price: 92 EUR

The power supply has big capacitors.
If electricity on external mains disappears, the power supply goes slowly down. A controller, which is attached to it, remains operational for about 3.7 second.
This is while standing still, and drawing little power.
With motor moving duration might be shorter.
During this time the controller may detect the power lowering gradually, and react accordingly.
For that to work, you would feed the 5V line additionally to the analogue I/O wire of TMCM303, and write a little standalone TMCL code for detection. The code would possibly save some data into data banks (into EEPROM), and do other procedures necessary for custom shutdown of the module on power loss.
An example of such application is here:
