Glassman MJ系列高壓電源
MJ Series 15 Watt Regulated High Voltage DC Modules.The MJ Series provides premium 15 W performance at low cost in a small ａnd lightweight package.This series, with air insulation for easy serviceability,should not be confused with competitive encapsulated units that must be discarded if faulty. Voltage ranges,depending on model, are from 0 to 3 kV through 0 to 30 kV.
Glassman MJ系列高壓電源特點
From 5% to 99% 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), single-phase,48-420 Hz, <0.25 A. 3-position terminal block with cover. OUTPUT:
Continuous, stable adjustment from 0 to rated voltage/current by external 0 to +10 V signal, external potentiometer, or case-mounted 10-turn potentiometer with 0.05% resolution. Accuracy, 1% rated +1%setting. Repeatability better than 0.1% fs.
STORED ENERGY: <200 millijoules, 15 kV model; <400 millijoules, 30 kV model. VOLTAGE REGULATION: Better than 0.005% from no-load to full load ａnd over specified input range. RIPPLE: <0.05% RMS of rated voltage at full load. Ripple proportional to load, decreasing to approximately 0.01% at no load. CURRENT REGULATION: Better than 0.05% from short circuit to rated voltage at any load condition. VOLTAGE MONITOR:
0 to +10 V equivalent to 0 to rated voltage.
Accuracy, 1% reading +1% rated.
CURRENT MONITOR:
0 to +10 V equivalent to 0 to rated current.
Accuracy:1% reading + 0.05% rated.
STABILITY:
0.01% per hour after 1/2 hour warmup, 0.05% per 8 hours.
VOLTAGE RISE/DECAY TIME CONSTANT:
50 ms typical (100 ms max.) with a 50% resistive load using either TTL on/off or remote control.
TEMPERATURE COEFFICIENT:
0.01% per degree C.
AMBIENT TEMPERATURE:
-20 to +60 degree C, operating;
-40 to +85 degree C, storage.
POLARITY:
Available either positive or negative 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.
REMOTE CONTROLS:
DB15S D-subminiature with mating plug is provided for all remote functions, including common, +10 V reference, interlock,voltage and current program/monitor, TTL,ground, and local control.
EXTERNAL INTERLOCK:
Open off, closed on.
TTL ENABLE/DISABLE:
0-1.5 V off, 2.5-15 V on.
