GENERAL TECHNICAL CHARACTERISTICS
1) MAINS INPUT
180 - 264 V a.c. 50 Hz (Europe)/ 80 - 130 V a.c. 60 Hz (U.S.A.).
2) DEGAUSSING
Automatic at switch on. 220-240 V a.c.
±
20% (Europe); 110 V a.c.
±
20% (U.S.A.).
3) INPUT POWER
With 90° c.r.t. at maximum contrast and brightness, 80 W (1.3 A)
With 110° c.r.t. at maximum contrast and brightness, 100 W (2
A)
4) INRUSH CURRENT
<
25 A peak.
5) VIDEO INPUT SIGNAL
RGB positive going with input inpedance of 1 kQ. Sensitivity 1.5 - 4.0 V p.p.
6) VIDEO BANDWIDTH
15 MHz -3 dB.
7) HORIZONTAL FL YBACK TIME
11 .5 µs .
8) VERTICAL BLANKING PERIOD
0.9 ms.
9) SYNC . INPUTS
Horizontal and vertical, positive and negative, composite or separate with automatic selection. Input
impedance 1 kQ. Input level 1.5 - 4 V p.p.
10) HORIZONTAL AND VERTICAL SCANNING FREQUENCIES
Horizontal 15,700
±
500 Hz adjustable.
Vertical 45 - 65 Hz adjustable.
11) WORKING TEMPERATURE
0 - 50°C
12) MONITOR CONTROLS
Horizontal frequency-phase-amplitude-linearity; vertical frequency-shift-amplitude-linearity; contrast,
brightness, focus, trapezium and pin cushion correction and d.c. deflexion control. (The d.c. line voltage
of POLO monitors is factory adjusted and should never be alterated by the adjustment potentiometer. Other
feed voltages are dependent upon this setting and incorrect setting will result in faulty operation and will
affect reliability. For checking voltages see the attached circuit diagram) .
Adjustment of horizontal amplitude stretches the image, permitting the display of signals with an
active video time of only 39 µs .
