General
The Series 815 and 835 are high efficiency switchmode, fixed
output polarity, modular high voltage power supplies that feature constant
voltage and constant current operation with automatic crossover. A wide range
of output voltages, up to 50kV, is available. Designed for safety and reliability,
all models include a safety interlock, soft start and power interrupt trip,
as well as arc, short circuit and open circuit protection. These supplies
provide high performance and value in many applications including detectors,
projection CRT's, X-ray, electrophoresis, microwave and capacitor charging.
The units are fully enclosed and designed for system or bench top use. They
operate off of standard line input of 115/230 Vac (switch selectable) 50-60
Hz. The output voltage and output current are independently controlled by
internal multi-turn potentiometers. Remote analog voltage or resistance programming
of both the output voltage and current is included in all models. Analog monitor
outputs are also provided for remote monitoring of both the high voltage and
current outputs. A front panel LED indicator provides power ON status.

185 - 265Vac @ 1.5A (815), 3A (835), 50-60Hz.
Performance
Voltage Regulation:
± (0.01% of setting + 0.01% of maximum) for ± 10% input line change.
± (0.02% of setting + 0.02% of maximum) for FL-NL and NL-FL change.
Current Regulation:
± (0.05% of setting + 0.05% of maximum) for ± 10% input line change.
± (0.1% of setting + 0.1% of maximum) for 0 to maximum rated output voltage change.
Ripple:
0.1% of setting + 0.1% of maximum, peak-to-peak. Lower ripple available on many models. Consult factory for details
Temperature Coefficient (0 to 50°C):
Constant voltage operation:
± (50ppm of setting + 50ppm of maximum)/ °C
Constant current operation:
± (100ppm of setting + 100ppm of maximum)/ °C.
Storage Temperature:
-40°C to +85°C
Stability (after 1/2 hr. warm-up):
Constant Voltage Operation:
± (0.01% of setting + 0.01 % of maximum)/hr; ±(0.02% of setting + 0.02% of maximum)/8 hrs.
Constant Current Operation:
± (0.02% of setting + 0.02% of maximum)/hr; ± (0.04% of setting + 0.04% of maximum)/8 hrs.
Efficiency:
Better than 80%.
Features
Internal Controls:
Independent precision multi-turn potentiometers for voltage and current control. The potentiometers are screwdriver adjustable and easily accessed.
Remote Programming:
Two independent 0 to 5Vdc inputs for 0 to maximum voltage and current outputs. Accuracy is ± (0.2% of setting + 0.2% of maximum).
The programming input impedance is greater than 1 megohm. The program inputs are differential. This feature provides user defined program voltage polarity and eliminates ground loops.
Voltage Monitor:
0 to +5Vdc proportional to 0 to maximum output high voltage. Accuracy is ± (0.2% of reading + 0.2% of maximum). The monitor output impedance is 10 kilohms ± 1%.
Current Monitor:
0 to +5Vdc proportional to 0 to maximum output current. Accuracy is ± (0.5% of reading + 0.2% of maximum). The monitor output impedance is 10 kilohms ± 1%.
Interlock:
TTL compatible remote signal disables (high), enables (low) the high voltage output. The enable input must be pulled low to allow operation of high voltage, regardless of whether supply is in local or remote mode.
Protection:
Arc, short circuit and open circuit protection, self restoring.
