TTi PL330QMD - Presný laboratórny zdroj s lineárnou reguláciou 32V/3.1A (190W)

OVERVIEW

The Thurlby Thandar PL series of laboratory bench power supplies has established itself in many countries as an “industry standard” range.

Digital accuracy and convenience
PL series units incorporate digital meters with a 3.75 digit scale length (4095 counts) to provide greater accuracy and resolution than other PSUs.
Large and bright LEDs give a clear and unambiguous reading. An update rate of 4 per second provides near instantaneous response.
Separate meters are used for voltage and current, eliminating the need for meter function switches with their attendant problems of misinterpretation.
A damping switch for the current meter simplifies measurements on rapidly varying loads.

Remote sense for precision at high currents
Remote sense terminals enable the precision to be maintained at high currents by eliminating the effects of connection lead resistance.
Without remote sense lead resistance of just a few tens of milliohms can seriously degrade regulation and produce misleading results. (Two cables of 0.05W each will drop a total of 0.3V at 3 Amps.)

Safety and protection
PL series PSUs are designed and built to meet the stringent requirements of IEC348 and IEC1010.
All outputs are fully protected against short circuit, reverse voltage and reverse currents.

Greater resolution and control
The PL series sets the standard for simple and comprehensive control. Voltages are set with coarse and fine controls for speed with precision. Currents are set with a semi-logarithmic control for increased resolution at low current levels.
The DC output switch enables voltage and current levels to be set before the load is connected. With the output switch “off” the the current limit set point is displayed. With the output switch “on” the actual output current flowing is displayed.
This invaluable feature allows delicate circuits to be protected by accurately setting the current limit level (down to a few milliamps if necessary) before connecting the circuit under test.

Quad-mode duals and triples
The  32V-2A and 32V-3A supplies are each available as a dual unit incorporating push button selection of four modes of operation:

Isolated - 2 x single outputs

True Parallel - The Master acts as a single supply of twice the current capability.

Series - Outputs connected in series but with independent control.

Series Tracking - As series but both voltages are set with the Master voltage control.

Each of the quad-mode dual models is alternatively available as a triple supply incorporating one further independent output. This is a higher current 5 Volt output intended for powering logic circuits.
