xiamen machinery fair"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," said Mark Edwards, sales director of TTi. "The original PL quad-mode dual supply has been one of this company's most successful products, and we 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 30V at 0 to 3A, 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 0.4 mV 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.

Built-in customization board, red laser fast selling players Most monitors derive the high voltage for the CRT second anode (THE high voltage - called EHV by some), focus, and (sometimes) screen (G2) from the horizontal-deflection system [ILLUSTRATION FOR FIGURE 1 OMITTED]. That technique was developed quite early in the history of commercial TV and has stuck for a very simple reason - it is very cost effective. A side effect is that if the horizontal deflection fails and threatens to bum a vertical line into the CRT phosphors, the high voltage dies as well. Of course, if the vertical deflection dies.... Some auto-scan workbench use a separate high-voltage supply. One reason for that approach is to decouple the horizontal deflection from the HV in auto-scan monitors, thus simplifying the design. Usually that supply is a self-contained inverter module. It if can be opened, then repair may be possible. With a separate HV supply, there is no need for a HV flyback transformer on the mainboard. Some designs may use a separate HV supply including a flyback, which is part of the mainboard but is self contained and independent of the horizontal-deflection system. Most TV and monitor (flyback) high-voltage supplies operate as follows: 1. The electronic workbench turns on during scan. The current increases linearly in the primary of the flyback transformer since it appears as an inductor. The magnetic field also increases linearly. Note: the flyback is constructed with an air gap in the core, which makes it behave more like an inductor than transformer as far as the primary workbench is concerned. 2. The HOT shuts off at the end of the scan. The current decreases rapidly. The magnetic field collapses, inductively coupling to the secondary and generating a HV pulse. The inductance and capacitance of the flyback, snubber capacitors, and parasitic capacitance of circuitry and yoke form a resonant circuit. Ideally, the voltage waveform across the HOT during the flyback (retrace) period will be a single half cycle, and it is clamped by a damper diode across the HOT to prevent undershoot. |
