Queralt 010418 EP04-99 ECLER PAM4/6100 author: date: project: product: approved: title: FUNCTIONING DESCRIPTION 52.0010 01.00 num: version: EPO4-99 Power Module. Functioning description. Due to the high power level required on the output load, the amplifier final stage's structure differs from the design used untill now. This is due to the breakdown voltage limit on P-channel MosFET's, wich is 200V.
Page 5
Transistors Q111 and Q112, and their corresponding twins at the lower branch, form a current-buffering circuit wich allows a fast charge and discharge of the power MosFET's gates. The Zobel circuit, a resistance-capacitance-inductance formed network associated to the amplifier's ouput, tries to keep the amplifier's output load impedance constant no matter wich load value is conected to the output, or wich frequency is processed, in order to avoid phase shifts on the feedback signal.

This delay time is achieved by using a RC cell, where R135=287K and C119=47mF/50V. As this cell charges, its voltage increases untill reaching the 40106- type Schmidt trigger (IC108) switching value; at this point, the relay opens and the amplifier starts to function normally. The discharge or reset of capacitor C119=47mF can be done by cutting off the power supply, or by triggering the Thermal or other protections.

Once the nominal mains voltage is reached, wait for a minute and verify that the current consumption adjustments remain correct: 300mA for PAM6100, 190mA for PAM4100. If this values have changed, rectify them. Once adjusted, seal the potentiometer with fixing lacquer.

PAM6100 2200W 132,6V for PAM4100 Only channel I's input potentiometer should be active. Verify that the amplifier reaches its clipping state without troubles. Return the unit to its STEREO operating mode. Connect a load impedance formed by a 4Ω resistor shunted to a 2µ2F capacitor, and apply a 1KHz square waveform input signal.

DC OUT In order to run this test, do not connect any load impedance. Adjust the signal generator to deliver a signal with a frequency below 5Hz, and select the 3V scale output level. Connect the oscilloscope to the unit's output, 5V/div vertical scale, 20ms/div time base. Use a 10x attenuating test probe.

QUALITY CONTROL All mechanical parts should be visually revised, in order to detect scratches on the unit's painting; all screws should be on their place,correctly tight and unmarked. Check out the unit's general presentation. BURNING TEST Leave the tested units connected to the burning verifyer, while performing their burning test. If testing PAM 6100, do not connect more than 4 power stages to each column.
