Fb30 pressure switches are used to regulate tank pressure between two preset values on small (up to 175psi) electrically driven air compressors. Equipped with an unloader valve, they could prevent compressors from starting under load, and an auto-off disconnect lever for manual cut off the compressor. Both one and four-ports manifold style are available which provides easy mounting of valves and gauges.. 1) operating pressure range: 5bar-12 bar; 2) differential pressure range: 2bar 3) 20a, 240vac, 50hz 0.3kg, cartons
Projection screen interface ideal to control motorised projection screen (ac 220 v operated ). timmer controled : automatically gets off after 1.5 minutes (only for screen) can control set of tube lights (which are programmed in different zones). Saving cost of additional light control unit. can control any electronic / electrical gadgets / equipments which is 220v ac operated. can be used to switch (on÷ (off÷ audio video equipments installed in rack. Maximum load upto 1 kva Ac 220v / 50hz operated One motorised 220vac screen Three separate port for three different audio video sources
Temperature rise test panel for domestic switch Specifications Input supply : 230v ac + / - 10% , 50 hz single phase with mcb protection. Output : current source 0 to 50 a max Digital voltmeter : 3-1/2 digit 0 to 300v Voltage drop indicator with range selector. Digital temperature indicator with 12 channels. Current controller for maintaining the output current at pre-set value. Ct range selector for accurate measurements. Description The test panel is made to suit the specification as mentioned in is : 3854 of 1997 for temperature rise test. The test panel broadly comprises of : 1. Ac constant current source ( true rms ) for 50 amps max / 5v. 2. Universal servo controller, for controlling the output current with the help of motorised variac Assembly. 3. Digital ac voltmeter to read the primary voltage of the power transformer. It helps to eliminate the Possibility of hunting of motor with the help of primary tap selector switch. 4. Digital temperature indicator controller - 12 channels - with thermocouples, to read the temperature rise At different parts of the switches. 5. Digital ac voltmeter with terminals and three ranges - 0.2, 2.0 & 20 v to measure the voltage drop Across the switch terminals while passing the specific current. 6. Range selector switch for ct to measure more accurately the current for lower as well as higher range. 7. Push buttons for test on / off with output indicating lamps. 8. Mains on mcb 2p / 10 a.
