High Voltage Function Generators
Model 615-10
Model 615-10 AC/DC High Voltage FUNCTION Generator
The Trek Model 615-10 [formerly Model PM04015A] is a high voltage function generator consisting of a precision high voltage AC/DC generator and amplifier system with a 20 kV peak-to-peak capability. This high voltage function generator is used in a broad range of R&D and production applications which include providing operating potentials required for electrostatic charger roller devices as used in electrophotographic processes. This model can also be used in other applications that require a high voltage function generator with the capabilities provided by this unit.
Constant Voltage Mode
In the constant voltage mode, the 615-10 generates constant amplitude waveforms with or without DC bias over a range of ±10 kV (20 kV p-p) with a constant current output of ±35 mA peak, ±10 mA DC. A high slew rate capability of 500 V/ms provides low distortion of full output AC waveform of greater than 7.5 kHz (sine).
Constant Current Mode
In the constant current mode, the 615-10 generates constant amplitude AC current waveforms, with or without an added DC bias, over a range of 0 to ±10 mA with an output voltage compliance range of ±10 kV (20 kV p-p).
Amplifier Mode
In the AMPLIFIER mode, an analog voltage input connector is provided to apply external AC or DC signals to be amplified by the 615-10. Amplifier gain is fixed at 1000 V/V to provide up to 20 kV p-p voltages to the output terminal at ±35 mA peak, ±10 mA DC. The DC BIAS control circuitry is active while in the amplifier mode.
The Model 615-10 provides many extra features to provide versatility in operation such as voltage limiting control and current limiting control. The Trek exclusive I(s) control provides for termination of a load current path which is not to be monitored/controlled, such as electrophotographic corotron/scoratron device shield current. This feature allows tightly regulated ion charging current flow to the photoconductor surface without the need to monitor drum return current.
Voltage and current values are read by front panel displays or through rear panel buffered outputs providing low-voltage representations of the load current and the high-voltage output. A 25-pin “D” connector permits connection of TTL signals and 0 to +10 V DC analog signals to remotely control the operation of the Model 615-10.
