Low Noise Power Supply offers Dual and Single Output Modes

TTi have launched a dual output version of their new PL series linear regulated power supplies. The PL303QMD is the latest model in the New PL series of ultra low noise, and ultra compact PSUs which replace the original PL series.

Mark Edwards, sales director of TTi, commented:
“Despite the improvements in the performance of switch-mode based laboratory power supplies, demand for linear regulated models remains very strong, driven by the needs of low voltage circuitry and RF technology. The original PL quad-mode dual has been one of this company’s most successful products, and I expect the advanced features of the new model to expand the market further”.

Housed in a half-rack (212mm wide) casing, the PL303QMD has two identical outputs of 0 to 30 volts at 0 to 3 amps and uses significantly less bench space than other linear regulated PSUs of similar power.

Voltage and current are set using true analogue controls, but the settings can be locked at the touch of a button using the S-Lock function. The span of the analogue controls can also be changed using the V-Span feature.

Linear regulation provides noise of below 0.4mV rms with low peak to peak excursions and low common mode noise current. This ensures that the PL303QMD can be used in environments where many conventional power supplies would be unsuitable.

Quad-mode switching offers four modes of operation which include a single output mode in which all 180 watts of power is provided on one output of 0 to 30V at 0 to 6A.

In dual modes, the two outputs are always electrically isolated and can be set to be fully independent control or master-slave control with a fixed or variable ratio between the two outputs. Output isolation of these tracking modes enables the user to create two rails of either polarity and to reference them to different grounds if necessary (e.g. digital ground and analogue ground) offering maximum flexibility.

In addition to the individual switches for each output, switches are also provided to allow both outputs to be turned on or off synchronously by a single button press. Synchronous switching of the outputs is of increasing importance for circuitry which can be damaged if one voltage rail is present without the other.

The price in the UK is £499.
The approximate International prices is $1,000..
