Voltage sensor-ACPL-C87x

Avago Technology presents a new category of optically-isolated current devices, which can be eye remoteness built-in amplifiers according to sigma-delta modulation which is particularly enhanced pertaining to voltage realizing. Focused on programs such as feeling voltages inside electric strength alteration techniques frequently found in electric motor hard disks, moving over electrical power supplies, and also sustainable energy programs, and also warning connects such as NTC thermistor seclusion within IGBT modules, the particular ACPL-C87B, C87A, as well as C870 supply designers using a 2-V input range and high 1 GΩ input impedance.

Regarding basic apps, the actual ACPL-C87A (±1% achieve patience) as well as the ACPL-C870 (±3% gain tolerance) are suggested. For high-precision software like alternative energy inverters in which it is very important precisely observe the rising and falling (due to changing sun situations) electricity coach current and then for high-performance servo along with motor hard disks, your ACPL-C87B (±0.5% acquire threshold) can be utilized. The voltage sensors comes with a 1V/V unity achieve with reduced obtain move involving -35ppm/˚C hemical and non-linearity is actually held for you to inside 2.1% maximum. The actual current receptors provide an active-high shutdown flag, which cuts down on IDD1 current to onlythrough standby, producing the particular receptors well-suited with regard to battery-powered and also other power-sensitive applications.

Avago Technologies’ Visual Solitude Amplifiers have owned innovative Sigma-Delta modulation technologies and chopper-stabilized amps to deliver correct, safe, and reliable present and voltage detecting for more than 20 years within motor pushes and electrical power converters. Differential outputs on the fresh gadgets supply extraordinary isolation-mode sound rejection, minimal offsets, substantial obtain exactness as well as balance, plus a wide transmission data transfer useage regarding 100 kHz.

The built-in tough safety padding and high CMR (typical function being rejected) functionality helps prevent mistaken current proportions and makes certain trustworthy function in the deafening setting. The optically-isolated voltage sensors possess a 15 kV/µs common-mode transient immunity. Security mortgage approvals consist of CSA along with IEC/EN/DIN EN60747-5-5 having a VIORM of a 1,230 Vpeak. Furthermore, your sensors are UL recognized together with 5,000 Vrms for 1 minute for every UL1577.

Your ACPL-C87x voltage sensors are stored throughout extend 8-lead SO-8 plastic-type material bundles using 8-mm creepage and wholesale in which satisfy international regulation basic safety standards. Your devices in addition have a extensive running temperature range of -40˚C to 105˚C.
