The MQ Series of 300 watt high voltage
supplies feature flexible embedded controls with low ripple and noise. They are
air insulated, fast response units, withtight regulation andextremely low arc discharge currents
Please refer to Technology > Applications
page onour web site for typical applications.
The MQ Series with F22 option, are fullycompliant with the Following European
Directives:
EN61000-3-2, Line Harmonics.
EN61010/ IEC61010, SafetyEN61000-6-4, Conducted and RadiatedEmissions
EN61000-6-2:2005, Conducted andRadiated Immunity
2011/65/EU, Restriction of the use ofHazardous Substances (RoHS)
CE (Meets all applicable directives), UKCA
(Meets all applicable legislation)

Models from 0 to 1 kV through 0 to 60 kV; Weight <20 lbs.
The MQ Series is a family of sophisticated, medium power, high voltage power supplies that complies with current international safety and EMI directives. We have packaged this series as a space saving module to avoid the expense of front panels and displays. However, no compromises in performance and/or operating features have beenmade. The result is a power supply that offers outstanding value for a wide range ofdemanding applications.

Features:Arc Quench. The HV output is inhibited
for a short period after each load arc to help
extinguish the arc.

Arc Count. Internal circuitry constantly
senses and integrates arcs that occur overa given time. In the event a system or load
arcing problem develops and exceeds factory-set parameters, the power supply will
cycle off in an attempt to clear the fault
and then automatically restart after a preset “off dwell time”.

Embedded Microcontroller control.
Integral RS-232, USB and optional ethernet
communications provide remote control
program and monitor.

Air Insulated. The MQ Series features

Constant Voltage/Constant Current
Operation. Automatic crossover fromconstant-voltage to constant-current regulation provides protection against overloads, arcs, and short circuits.

Low Ripple. Typically, ripple is less than
0.025% RMS of rated voltage at full load.

Tight Regulation. Voltage regulation isbetter than 0.005% for allowable line andload variations. Current regulation is better than 0.1% from short circuit
to rated voltage.
Constant Current/Current Trip. A connection made on the interface connector, allows
selection of either current mode.
Warranty. All power supplies are warranted
for three years. A formal warranty statement is available.

“air” as the primary dielectric medium. Nooil or encapsulation is used to impede serviceability or increase weight.

Specifications(Specifications apply from 5% to 100%

down to zero voltage with a slightdegradation of performance.)

Voltage accuracy is 0.2% of rated +0.5% of setting. Repeatability is < 0.1%of rated.
Static Voltage Regulation: Better than
±0.005% for specified line variations
and 0.005% + 0.5 mV/mA for no load
to full load variations.
Dynamic Voltage Regulation: Forload transients from 10% to 99%
and 99% to 10%, typical deviation isless than 2% of rated output voltage
with recovery to within 1% in 500 us
and recovery to within 0.1% in 1 ms.
Ripple: Better than 0.025% of rated
voltage + 0.5 V RMS at full load.
Current Regulation: When in current
regulation mode, better than 0.1%
from short circuit to rated voltage
at any load condition.
Voltage Monitor: 0 to +10 V
equivalent to 0 to rated voltage.
Accuracy: 0.5% of reading + 0.2%of rated. Impedance is 10 KW.
Current Monitor: 0 to +10 V equivalent
to 0 to rated current. Accuracy: 1% ofreading + 0.1% of rated. Impedance is10 KW.

Stability: 0.01% per hour after 1/2 hourwarm-up, 0.05% per 8 hours.

RS232/USB/Ethernet Programming andMonitor Accuracy:

Voltage Rise/Decay Time Constant:
The voltage rise time constant is 50 mstypical for all models using either HVenable or remote programming control.
The voltage decay time constant is 50
ms with a 50% resistive load for 12 kV
to 60 kV models and 50 ms with a 10%
resistive load for 1 kV to 6 kV models.

Resolution: 0.025% of full scale forboth the voltage and the current
programs. 0.1% of full scale forboth the voltage and the current
monitors

Temperature Coefficient: 0.01% /°C.

Remote reading accuracy: Voltage
reading accuracy is 0.5% of reading+ 0.2% of rated. Current reading
accuracy is 1% of reading + 0.1% ofrated.

Ambient Temperature: -20 to +40° C,operating; -40 to +85° C, storage.
Polarity: Available with either positiveor negative polarity with respect to chassis ground.
Protection: Automatic current
regulation protects against all
overloads, including arcs and shortcircuits. Thermal switches and RPM
sensing fans protect against thermal
overload. Fuses, surge-limiting
resistors, and low energy components
provide ultimate protection.
Arc Quench: An arc quench featureprovides sensing of each load arc andquickly inhibits the HV output forapproximately 20 ms after eacharc. Standard on 8 - 60 kV models;
optional on 1- 6 kV models.
Arc Count: Internal circuitry senses thenumber of arcs caused by external load
discharges. If the rate of consecutive
arcs exceeds approximately one arc persecond for five arcs, the supply willturn off for approximately 5 seconds toallow clearance of the fault. After thisperiod the supply will automatically
return to the programmed kV value
with the rise time constant indicated.
If the load fault still exists, the above
cycle will repeat. Standard on 8 - 60 kVmodels; optional on 1- 6 kV models.
External Interlock: Open = off,
closed = on. Non-latching.
Remote HV Enable/Disable:
0 - 1.5 V = OFF, 2.5 - 15 V = ON.
