|Models from 0-8kVDC through 0-60kVDC; weight <20 lbs.
|Fully compliant with the European harmonized EMI directive, EN50082-2,
and with the low voltage (safety) directive, 73/23/EEC. The optional input line active power factor correction reduces
harmonic currents below those specified in EN61000-3-2.
- Medium Power
- Premium Performance
- Low Cost
The ML 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 been made. The result is a power supply that offers outstanding
value for a wide range of demanding applications.
High Speed Dynamic Voltage Regulation. For load transients of 10% to
99% and 99% to 10%, the output voltage will recover to within 1% in less than 1ms.
Low Ripple. Ripple is less than 0.05% of rated voltage at full load.
Low stored Energy. Most models exhibit less than one joule of stored
Air Insulated. The ML Series features "air" as the primary
dielectric medium. No oil or encapsulation is used which would impede serviceability or increase weight.
CV/CC/CT Operation. Automatic crossover from constant-voltage to
constant-current regulation provides protection against overloads, arcs, and short circuits. Current mode
operation is user configured for constant current regulation or current trip operation.
PFC Option. Assures compliance with EN61000-3-2.
Local Control. User designated ten-turn potentiometer control
provides the capability for local control of output voltage or current.
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.
(Specifications apply from 2% to 100% of rated voltage. Below 2% of rated
voltage a slight degradation of ripple, regulation, and stability may occur.)
Input: 90-132VAC single-phase, 48-420Hz, 600VA maximum. Connector per
EC 320 with mating line cord terminated with NEMA 5-15 plug.
Efficiency: Typically 85% at full load.
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. Linearity is < 1% of rated. Accuracy is 0.1% of rated + 0.5% of setting. Repeatability is <
0.1% of rated.
Current limiting/Current Trip: User selectable at interface control
connector for either "trip" operation or normal current limiting. If "trip" operation is
selected the power supply will latch off in the event the load current exceeds the current "set"
Stored Energy: See Models chart. The stored energy includes the
capacitance f the standard 8' output cable which is approximately 300pF.
Static Voltage Regulation: Better than 0.005% for specified line and
Dynamic Voltage Regulation: For load transients from 10% to 99% and
99% to 10%, typical deviation is 2% of output voltage with recovery to within 1% in 1ms, and to 0.1% in 2ms.
Current Regulation: Better than 0.1% of rated current from short
circuit to rated voltage at any load condition.
Ripple: <0.05% rms of rated voltage at full load.
Voltage Monitor: 0 to +10V equivalent to 0 to rated voltage. Accuracy,
0.5% of reading + 0.1% rated.
Current Monitor: 0 to +10V equivalent to 0 to rated current. Accuracy,
1% of reading + 0.1% rated.
Stability: 0.01% per hour after 1/2 hour warm-up, 0.05% per 8 hours.
Voltage Rise/Decay Time Constant: 400ms typical with a 5% resistive
load using either the HIGH VOLTAGE ENABLE input or remote programming control.
Temperature Coefficient: 0.01% per °C.
Ambient Temperature: -20 to +50°C, operating; -40 to +85°C, storage.
Polarity: Output polarity is available as either positive or negative
with respect to chassis ground.
Protection: User selected automatic current regulation or current trip
protects against all overloads, including arcs and short circuits. Fuses, surge-limiting resistors, and low
energy components provide ultimate protection.
Accessories: Detachable 8' HV coaxial output cable, 6' detachable
line cord, and mating control connector.
Interface Control Connector: Twenty-five pin "D"
sub-miniature connector. As standard, all ML Series supplies provide output VOLTAGE AND CURRENT PROGRAM/MONITOR
(0-+10V = 0-fs), HIGH VOLTAGE ENABLE (0-1.5V off, 2.5 -15V on), HIGH VOLTAGE STATUS (high = HV on, low = HV off),
SAFETY INTERLOCK (open = off, closed = on), CURRENT TRIP/ LIMIT select, +10 VOLT REFERENCE source, V/I MODE
STATUS (high = voltage mode, low = current mode), LOCAL CONTROL, COMMON and CHASSIS GROUND.
||AC input line, rated 180-264VAC, 48-420Hz. Mating line cord terminated with a NEMA 6-15 plug.
||Slow start ramp. Specify standard times of 5,10,15,20, or 30 Sec, ±20%.
||0-5 V voltage and current program/monitor.
||Power-Factor Corrected. AC input line, rated 180-264VAC, 48-63Hz, 400VA maximum. Active correction circuitry achieves an input line current harmonic content well below the maximum specified in EN 61000-3-2.
