1.1 Description of the V6 Series
S
pellman’s V6 Series is a family of regulated, fixed
output polarity module high voltage power supplies which
provide exceptional performance and value in many
applications. Utilizing proprietary power conversion
technology these SMT based high voltage modules
provide improved performance, reliability and easy
system integration. The V6 series units are fully enclosed
and designed for system or bench top operation.
The V6 is rated at 30 watts with output voltages spanning
from 1kV to 30kV with fixed positive or negative
polarities. Voltage & Current loops with automatic cross
over control regulate the output into any load condition.
The output voltage is controlled locally by an internal
multi-turn potentiometer. Remote analog voltage and
current programming capability are included in all
models. Analog monitor outputs are also included for
remote monitoring of output voltage and current. The V6
is a reliable and robust series that is arc and short circuit
protected. The comprehensive standard interface provides
interfacing flexibility and all V6 units are CE, UL and
RoHS compliant.
1.2 Standard Features
The V6 Series incorporates several standard features
designed to optimize user satisfaction and safety:
●Current Regulating Loop:
Current programmability
allows the user to set where the unit will current limit,
anywhere from 0 to 100% of maximum rated current.
● 0 to +
5Vdc Remote Programming Inputs:
Positive
polarity, high impedance, ground referenced 0 to 5Vdc
voltage programming inputs correspond to 0 to 100%
rated voltage and current outputs.
●
Local Control:
Multi-turn potentiometer located on the
top of the unit is provided to control the output voltage
locally.
● 0 to +
5Vdc Monitor Outputs:
Positive polarity, low
impedance, ground referenced 0 to 5Vdc voltage monitor
outputs correspond to 0 to 100% rated output voltage and
current.
● Precision +5Vdc Reference Output:
A precision
micro power band gap reference of +5Vdc, ±0.5%,
25ppm/°C is provided to simplify remote programming of
the power supply.
● Arc and Short Circuit Protected:
Due to the fixed,
high frequency conversion rate the V6 series output
capacitance is small resulting in minimal stored energy.
Through the use of generously rated surge limiting
resistors and a fast acting current loop, all units are fully
arc and short circuit protected.
1.3 Remote Operating Features
● Enable Input:
The Enable Input allows the user to
easily control the HV ON/OFF status of the power supply.
HCMOS compatible signals A low (<1.5Vdc) enable
input signal equals HV ON, while a high (open or >3Vdc)
enable signal equals HV OFF.
Warning
!
The Enable Input should not be used as
protection against user injury or for a safety
interlock function.
1.4 Option
RS232 interface is available
