TDK Lambda EMS 30-165-2-D-RSTL Power Supply
The TDK Lambda EMS 30-165-2-D-RSTL Power Supply includes an overvoltage trip set-point set by potentiometer R8. The output voltage is perceived by R26 and R27. The amplifier has a positive feedback loop, which needs AC extraction power to restart after the OVP has been activated. C23 prevents noise tripping from the latch. Once pin 8 of U4 is blocked, Q5 turns on and the control pin is lowered, causing the modulator to close. Also, Q8 is activated and the output of the power supply is crowbarred. The OVP LED is lit through J3 / 8 for 600W / 1KW and through J3/12 for 2KW / 2.5KW and 5KW.
The EMS 30-165-2-D-RSTL also incorporates a Mode Detect; R38 samples the voltage at the output of U6. In the 600W/1KW and the 2/2.5KW, U4 contrasts the output of the voltage channel to GND (zero), while in the 5KW the voltage channel is contrasted to the current channel through R39. When the voltage channel is in control, the output of U4 at pin 14 is high and that lights the Voltage Mode Led through R41. If the Current Channel is in control, the output of U4 at pin 14 is low and the Current Mode Led lights through R40.
Remote Turn-on is a feature that permits the user to control the power supply from a remote location with either 12-24 Vdc or 24-115 Vac or a dry contact closure. U3 (U2 for the 5KW) offers isolation from the power supply ground. With the internal LED of U3 (U2) not triggered, Q4 is turned on, which shuts down the modulator through CR12 and Q5.
This model offers a Maximum Voltage Output of 30 V and a Maximum Current Output of 165 A.
