Glassman LH系列高压电源
LH Series 5 kW Regulated High Voltage DC Power Supplies 1 kV to 100 kV Rack Mount CE Compliant.The LH family of power supplies are sophisticated, 5 kW, high voltage power supplies with low ripple and noise. They are air insulated, fast response units, with tight regulation. ArcQuench and Arc Sense are features that make the LH series Ideal for Dynamic load environments.
The LH Series are fully compliant with the European Harmonized EMI Directive EN50082-2 and with the European Low Voltage (Safety) Directive, 73/23/EEC.Glassman LH系列高压电源特点
From 5% to 99% rated voltage. All units operate down to zero output with very slight degradation of performance.
INPUT:
187-264V RMS, 3-phase, 48-63 Hz, 6500 VA maximum at full load. Less than 20 A/per phase. at 208 VAC. A five position rear terminal block with protective cover is provided.
EFFICIENCY:
Typically greater than 85% at full load.
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 10 V signals is provided. Linearity is < 1% of rated. Voltage Accuracy is 0.5% of setting + 0.2% rated.
STATIC VOLTAGE REGULATION:
Better than ±0.005% for specified line variations and 0.01% for no load to full load variations.
DYNAMIC VOLTAGE REGULATION:
For load transients from 10% to 99% and 99% to 10%, typical deviation is less than 2% of rated output voltage with recovery to within 1% in 500 μs and recovery to within 0.1% in 1 ms.
RIPPLE:
Better than 0.05% RMS of rated voltage at full load.
CURRENT REGULATION:
When in current regulation mode, better than 0.1%, with 8-100kV models better than 0.2%, from short circuit to rated voltage at any load condition. When in current trip mode the HV output will disable and latch off when the load current reaches the programmed current level. Reset is accomplished by either cycling the AC power or HV ON/OFF buttons, or by toggling the HV enable signal. A switch located on the rear panel allows the selection of current limit modes: onstant current, or current trip.
VOLTAGE MONITOR:
0 to +10 V equivalent to 0 to rated voltage.
Accuracy, 0.5% reading + 0.2% rated.
Impedance is 10 K.
CURRENT MONITOR:
0 to +10 V equivalent to 0 to rated current.
Accuracy: 1 kV to 6 kV: 1.5% of setting plus 0.5% of rated output.8 kV to 100 kV: 1% of setting plus 0.2% of rated output. Output impedance is 10K Ohm differentially coupled.
