Laboratory

Power supplies with adjustable output voltage and current, for use in workshops.

T3005D 
5A Laboratory power supplier

This is a laboratory source capable of supplying a voltage between 0 and 30V with a current between 0 and 5A. This power supply has two displays that show voltage and current.

It has 4 dials for adjusting voltage and current. One control adjusts one of its parameters in full scale, while the other allows a fine adjustment.

These sources are linear, but the transformer's secondary winding has several outputs, automatically switched with a relay, thus reducing consumption at low voltages.

It has LEDs that indicate power failure or current outage.

Features:

  • Input voltage: 220V + -10% 50Hz-+-2Hz

  • Adjustable output voltage: 0-30V

  • Adjustable output current: 0-5A

  • Source regulation: CV 2x10-4 +1 mV, CC 5x10-3 +1 mA

  • Load regulation: CV 2x10-4 +7 mV rms (I rated <= 3A), CV-3 5x10 +27 mV (I rated> 3A)

  • Noise level: CV <1 mV rms (I rated> 3AH) CV> = 1mV rms (I rated> 3AH) CC <5mA rms (I rated <= 3AH) CC <10mA rms (I rated> 3A)
  • Protection: protection margins: unlimited current stream

  • Accuracy of voltage indication: LCD ± 1% digital digits.

  • Accuracy of current indication: LCD ± 1% digital digits.
