The MK Series of 15 watt high voltage
air insulated, fast response units, with tight regulation and low arc
Please refer to Technology > Applications page
on our web site for typical applications.
Current Regulation Unequalled in a Module of This Price
Range. For example, the regulation from short circuit to rated voltage for the 15 kV, 1
mA model is ± 500 nanoamperes.
Glassman's "Air Insulated" designs
are completely serviceable; this module is not an epoxy block "throw away".
AC Input: Eliminates the need, and expense of an
auxiliary DC power source.
Standard Accessories: Detachable 8' shielded
output cable, and mating control connector.
Constant Voltage/Current Operation - Standard
Low Stored Energy: Less than 200 millijoules for most models.
"Multi-Mode" operation permits maximum user flexibility.
- Local Voltage or Current Control, user selectable.
- Remote Voltage and/or Current Control via 0 ~ +10 Volt signal.
- Remote Voltage and/or Current Control via potentiometers.
Protection: Overload, short circuit, and arc protection
is provided by automatic current regulation and by careful surge limiting design.
External Interlock Terminals
Warranty. Standard power supplies are warranted for
three years; OEM and modified power supplies are warranted for one year. A formal warranty
statement is available.
(From 5% to 100% rated voltage. All units operate down to zero
output with very slight degradation of performance.)
Input: 105-125V RMS or 210-250V RMS
(must be specified when ordering),
48-63Hz single phase, 0.25 amperes. 3 position terminal block with cover
provided. 400Hz input available. (DC input available for quantity orders -
Output: Continuous, stable adjustment,
from 0 to rated voltage or current by panel mounted 10-turn potentiometer with
0.05% resolution, or by external 0 to 10V signals is provided. Voltage accuracy
is 1% of setting + 0.5% of rated. Repeatability is <0.1% of rated.
Stored Energy: 15kV model, < 200 millijoules; 30kV model,
< 400 millijoules.
Voltage Regulation: Better than 0.005% line and load.
Ripple: < 0.05% RMS of rated voltage at full load. Ripple is
proportional to load and decreases linearly to approximately 0.01% at no load.
Current Regulation: Better than 0.1% from short circuit to rated
voltage at any load condition.
Voltage Monitor: Zero to + 10V DC signal
is provided for zero to rated voltage. Accuracy is 1% of reading + 0.5% of
rated. Output impedance is 10 K.
Current Monitor: Zero to +10V DC signal
is provided for zero to rated current. Accuracy, 1% of reading +0.05% of rated.
Output impedance is 10 K.
Stability: 0.01% per hour. after 1/2 hour warm-up. 0.05% per
Voltage Rise/Decay Time Constant: Using either the HV on/off
or remote voltage control, with a 50% load, the output voltage will rise or decay with a typical time
constant of 50 milliseconds (100 mS maximum).
Temperature Coefficient: 0.01% per degree C.
Ambient Temperature: -20 degree C to +60 degree C, operating;
-40 degree C to +85 degree C storage.
Polarity: Available with either positive or negative polarity
with respect to chassis ground.
Protection: Automatic current regulation protects the power
supply against all overload conditions, including arcs and short circuits. Fuses, surge limiting resistors,
and low energy components provide the ultimate protection.
Output Cable: Detachable, 8 foot. RG8U shielded high voltage
coaxial cable is provided.
Controls: A DB15S D-subminiature connector, and mating plug,
is provided for all control input functions. These include common, + 10 volt reference, interlock,
current monitor, current program, voltage monitor, voltage program, TTL, ground, and
External Interlock: Open off, closed on.
HV Enable/Disable: 0-1.5 V off, 2.5-15 V on.
