|Models from 0 to 1kV through 0 to 60kV, 3.5" H x 19" W x 20.5" D, 22 lbs
|Fully compliant with the European harmonized EMI
directive, EN50082-2,and with the low voltage (safety) directive, 73/23/EEC.
- 1 to 60kV, 3.5" Panel
- Power Factor Corrected to >0.995
- Harmonics Well Below EN61000-3-2
The EQ Series are sophisticated, 1.2kW, high
voltage power supplies in a small and lightweight package. They are designed to
meet the growing demands from both users and electric utilities for switching
power supplies with excellent input power factors that draw harmonic currents
below those specified in EN61000-3-2. unit.
Power-factor Corrected. Active correction circuitry achieves
an input line current harmonic content well below the maximum specified in EN61000-3-2.
Arc Count. Internal circuitry constantly senses and
integrates arcs that occur over a 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."
Low Stored Energy. Most models exhibit less than 2 joules
of stored energy.
Single-phase Input. Full 1.2kW output from a single-phase,
198-264V, 48-63Hz input, 1420VA maximum.
Pulse-Width Modulation. Off-the-line pulse-width modulation
provides high efficiency and a reduced parts count for improved reliability.
Air Insulated. The EQ Series features "air" as the primary
dielectric medium. No oil or encapsulation is used to impede serviceability or increase weight.
Constant Voltage/Constant Current Operation. Automatic
crossover from constant-voltage to constant-current regulation provides protection against overloads,
arcs, and short circuits.
Low Ripple. Ripple is typically less than 0.02% of rated voltage at
Tight Regulation. Voltage regulation is better than 0.005%
for allowable line and load variations. Current regulation is better than 0.1% from short circuit
to rated voltage.
Front Panel Controls. Separate 10-turn controls with locking
vernier dials are used to set voltage and current levels. A high voltage enable (on) switch and an
AC power on/off switch complete the panel controls. L.E.D.'s indicate when high voltage is on, the
output polarity, and whether the supply is operating in a voltage or current regulating mode. For the
blank panel version, only a power on/off switch is provided on the panel.
Small Size and Weight. EQ Series power supplies occupy only
3.5 inches of panel height. Net weight is less than 22 pounds.
Warranty. Standard power supplies are warranted for three
years; OEM and modified power supplies are warranted for one year. A formal warranty statement is
(Specifications apply from 5 to 100% rated voltage. Operation is
guaranteed down to 0% of rated voltage with a slight degradation of ripple, regulation, and
Input: 198-264V RMS, single-phase, 48-63Hz, 1420 VA maximum.
<7 A at 220 V. Connector per IEC 320 with mating line cord terminated with NEMA 6-15 plug.
Efficiency: Typically 85% at full load.
Power factor >0.995.
Output: Continuous, stable adjustment,
from 0 to rated voltage or current by panel mounted 10-turn potentiometers with
0.05% resolution, or by external 0 to 10V signals is provided. Voltage accuracy
is 0.5% of setting + 0.2% of rated. Repeatability is <0.1% of rated.
Stored Energy: See Models chart.
Static Voltage Regulation: Better than 0.005% for specified
line variations and 0.005% + 0.5 mV/mA for load variations.
Dynamic Voltage Regulation: For load transients from 10%
to 100% and 100% to 10%, typical deviation is 2% of output voltage with recovery to within 1% in
500 Ás and to 0.1% in 1 ms.
Ripple: <0.02% of rated voltage + 300 mV RMS at full
Current Regulation: 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% rated. Output
impedance is 10 kΩ.
Current Monitor: 0 to +10 V equivalent to 0 to rated
current. Accuracy: 1% of reading + 0.05% rated for fixed polarity, 1% reading + 0.1% rated for
reversible polarity. Output impedance is 10 kΩ.
Stability: 0.01% per hour after 1/2 hour warmup, 0.05%
per 8 hours.
Voltage Rise/Decay Time Constant: 50 ms typical with a
10% resistive load using either HV on/off or remote programming control.
Temperature Coefficient: 0.01% per degree C.
Ambient Temperature: -20 to +40 degrees C, operating;
-40 to +85 degrees C, storage.
Polarity: Available with either positive, negative, or
reversible polarity with respect to chassis ground.
Protection: Automatic current regulation protects against
all overloads, including arcs and shorts. Fuses, surge-limiting resistors, and low energy
components provide ultimate protection.
Arc Sensing: Internal circuitry senses the number of arcs
caused by flawed external load characteristics. If the rate of consecutive arcs exceeds
approximately 2 per second, the supply will turn off for approximately 2 seconds to allow clearance
of the fault and then automatically resume normal operation. Custom modifications of this
feature are available. Consult the factory.
Remote Controls: Terminal block is provided for all remote
functions, including common, +10V reference, interlock, voltage and current program/monitor, HV
enable, ground, and local control.
External Interlock: Open off, closed on. Normally latching
except for blank panel version where it is non-latching.
Remote HV Enable: 0-1.5 V off, 2.5-15 V on.
||200 V ▒ 10% input, 48-63 Hz, maximum

||Blank front panel, power switch only.
||Current trip. Power supply trips off
when the load current reaches the programmed level. This option has a rear panel switch that
selects either "trip" operation or current limiting.
||Zero start interlock. Voltage control,
local or remote, must be at zero before HV will enable.
||Slow start ramp. Specify standard times of 1,
