Description: Vacuum luminescent indicator IV-27M is a low-voltage multi-digit indicator of a triode system with a directly heated cathode, green glow color and flexible leads, designed to display digits and a decimal point simultaneously in 13 digits and sign information in the 14th digit. The IV-27m indicator is intended for operation in the dynamic indication mode. Parameter Digital Discharge Brightness (2-13) not less 180cd / m² Brightness of one digit (1.14) not less 10cd / m² Uneven brightness of digital bits - with a brightness level of the minimum luminous discharge up to 250cd / m2 not more ± 40% - with the brightness level of the minimum luminous discharge 250-500cd / m2 not more + 60% -40% - with the level of brightness of the minimum luminous discharge over 500cd / m2 is not standardized Filament current not less 160mA not more 220mA Display segment current pulse of one digit (total) not more 2.5mA Single-discharge grid current pulsed not more 3-4mA Filament voltage 3.15V (nominal) Voltage of anodes (segments) and grids 24V (nominal) Operating instructions for the IV-27M indicator: It is not recommended to operate the indicator when the heater is supplied with direct current. The filament should be supplied with alternating current from the transformer winding with a midpoint. The midpoint is connected to the common wire (minus) of the circuit. To avoid image flickering, the switching voltage must be at least 40Hz. It should be borne in mind that the visible luminescence of the segment when the voltage is applied to the grid occurs at a positive potential of the anode-segment of about 2.5-5.0V. In order to avoid possible illumination, the potential value at the anode segment should not exceed 1.5-2.0V. To completely remove the glow of the elements of the anodes-segments when the voltage is applied to them, it is necessary to apply a locking negative potential of 2.5 to 5.0V to the grid. We recommend using a green filter.Combined shipping is accepted Contact me via message for any question Shipping time - 10-30 days Item will be shipped immediately after payment Thing will be securely packed Delivery from Ukraine by postal service Thanks for looking!
