Glassman PG系列高壓電源特點

    From 5% to 100% rated voltage. All units operate down to zero output with very slight degradation of performance.
INPUT:
105-125 V RMS, single-phase, 48-63 Hz,
<15 A. Series PG-LR: 208 V RMS +/- 10%, 3-phase, 48-63 Hz, <5 A.
EFFICIENCY:
Typically 75% at full load.
OUTPUT:
Continuous, stable adjustment from 0 to rated voltage and current by means of front panel 10-turn potentiometers,external zero to +10 V signals, or external potentiometers. Linearity to within 1% of full scale.
VOLTAGE REGULATION:
Better than 0.005% + 1 V, line or load.
RIPPLE:
Better than 0.1% of rated voltage at full load.
CURRENT REGULATION:
Better than 100 μA from short circuit to rated voltage for any load condition; 0.005% + 1 μA for line variations.
VOLTAGE/CURRENT MONITOR:
Zero to +10 V signal for zero to rated voltage/current.
STABILITY:
0.01% + 1 V per hour after 1/2 hour warmup,0.05% + 2 V per 8 hours.
TEMPERATURE COEFFICIENT:
0.01% per degree C + 1 V.
AMBIENT TEMPERATURE:
-20 to +60 degree C, operating;
-40 to +85 degree C, non-operating.
POLARITY:
Available with either positive, negative, or reversible (PG only) polarity with respect to chassis ground.
PROTECTION:
Automatic current regulation protects the power supply against all overload conditions,including arcs and short circuits. Fuses,surge-limiting resistors, and low energy components provide the ultimate protection.
EXTERNAL INTERLOCK:
Open off, closed on.
