Transducers 5708 1
Started by Tony Hodges
I'm looking for two different types of voltage transducers. Both would be used to provide analog inputs to a building management system. One transducer would be used for monitoring the voltage on a standard, single phase 120VAC circuit. One transducer would be used for monitoring the voltage on a bank of batteries (normal would be 48VDC) I'd prefer an output of 0-10vdc to the BMS system, but 0-5vdc, 0-20ma or 4-20ma would also work

DC Transducer 5534 1
Started by Tony Hodges
We are considering using a DC current sensor in an upcoming product for Solar Inverters. Here are the requirements: * Ability to sense DC current from 1 to 10A, with 5 or better accuracy. * Bandwidth from 0 to 10Hz. * Must be able to withstand fault currents up to 300ADC. * UL listed or recognized preferred. * Operating range from -20 to 60C.

Relay application question 5416 1
Started by Tony Hodges
This concerns your CR5395 current sensing relay system (the 'device'), applied to a charger system for an electric vehicle. The attached diagram reflects my current configuration, 'as built' (I contributed the diagram to Wikibooks). I will shortly be installing 8 small isolated chargers to float charge my 96 volt (16 x 6V) pack in order to reduce cooling fan wear and noise on the bulk charger. The in-vehicle bulk charger (K&W)is powered through a vehicle mounted relay ('Ry CP')whose purpose i...

3 Phase Active Power Transducer 5347 1
Started by Tony Hodges
I am looking for a 3 phase active power transducer, for a test system. The transducer must be approved for use in branch circuit in a UL 508 controller. I want to measure active power for some 3 phase motors. Motor data: Voltage 3x480V or 3x208V Frequency 50-60HZ Current 0-7A Output 0-10V or 4-20mA Is this something you have in your product range

3 Phase 4 Wire system 5289 1
Started by Tony Hodges
We have a 3-phase 4-wire system and would like to add the ability to measure individual line currents. This system operates at 400 Hz and we are expecting to never have to read over 15A per phase. This will be part of an automated test program. Currently we have 120 V 60Hz, 5VDC and 28VDC available as a power source. It would be greatly appreciated if you could point me to a part number that would work.
