Mumbai-based goliya instruments pvt ltd offersmanufactures digital panel meters. These digital panel meters that are available with re-scalable dip-switch.There are some general specifications of digital panel meters which includethese digital panel meters incorporate bright red 14.2 mm 7 segment led displays. 5a ac meters of these can be scaled for any range form 10 to 160 a in multiples of 10, and from 200 to 1,600 a in multiples of 100 a. These features , thereby reducesing inventory and storage cost of the digital panel meters. High quality components ensure accurate, reliable and consistent readings. Dimension of the instrument include; instruments are manufactured in standard din size 96 mm x 48 mm. The depth is only 100 mm thereby saving panel space. Some of the technical features are as follows;the measuring range of the dc variable ranges from 1.999 to 199.9 micron a, and the input impedance of this range is from 0.1 to 1 k ohm. The sampling time is about 0.4 sec and the frequency range is 45 to 400 hz for ac range. Power consumption is ac 5va and the operating temperature range is 0 to 50 deg c. Some of the specifications of the panel meters include are as follows:* display: 14.2 mm [0.56] h, red led * over range indication: 1 * auxiliary power source: ac 110 v / 220 v +/- 10 percent, 50 / 60 hz * storage temperature range: 1070 deg c * maximum relative humidity: 95 percent * dielectric strength [iec 688]: ac 2 kv / 1 minute, input to power terminals, ac 3 kv / 1 minute
