The IsoBand V brings forth a unique combination of high-isolation, high voltage measurement and high-bandwidth, making it a perfect choice in the industry for measuring fast transients, PWM switching, high-frequency signals, VFDs, surge voltages, sharp transitions, and more.
While keeping a bandwidth that spans from DC to 8MHz. It covers a large set of possible input ranges, from ±5V to ±2000V, which are isolated and linearly scaled to a standard ±10V output signal.
The IsoBand V modules provide a three-way galvanic isolation:
Channel to Channel
Primary to Secondary
Signal to Power
This galvanic barrier prevents unwanted currents from flowing along the circuit and adds a level of protection as well as allows to operate grounds with different potentials.
Compact Form Factor
The compact form factor of the IsoBlock I-ZF module set allows users to setup high channel density monitoring systems, making it ideal for high performance compact systems.
Flux Gate Methodology
The IsoBlock I-FG-4C uses Flux-Gate methodology to measure the current flowing through the input conductor. This technique works by placing a toroid with a high number of turns (secondary) around the input current path (primary), while a close-loop circuitry controls the current through the secondary to null out the magnetic field inside the toroid. The input current is then obtained by multiplying the current from the control circuitry by the number of turns of the secondary. This is followed by an anti-aliasing filter and a conditioning stage to output a ±5V signal.
Proprietary Digital Technology
The use of advanced analog to digital design unleashes the power of high bandwidth ADCs to deliver a signal conditioning device. This approach allows for the highest bandwidth on an isolated voltage transducer in the market.
High Input Impedance & Low Output Impedance
Verivolt's IsoBand V devices have a high input impedance that allows connecting them to most signal sources without a measurable impact. Also, the high input impedance increases device safety. The low output impedance makes it possible to connect to most digitizers and scopes as well as to run long wires.
High-Common Mode Rejection
The smart design of the isolation barrier is able to remove most common mode present in at the input. As a result, you get a cleaner output regardless of unwanted ground shifts or even AC components present at the input as common mode.
The IsoBand V devices are designed to survive and protect other equipment against harmful voltage surges. These depend on the duration but can go as high as 20x the rated measurement range for up to 5 microseconds.
IsoBand V devices will cap the outputs to a maximum slightly higher than the output range, saturate and not go over range therefore protecting any connected Digitizer or Scope.
Flat Frequency Response
The smart design and advanced materials help signals preserve their characteristics over a wide frequency range. As a result, the frequency response is very flat and the roll-off happens in a controlled way with the help of a 3rd order low pass filter.
The high linearity of the IsoBlock V makes possible to measure over a very wide amplitude range while preserving the nominal ratio. This high linearity associated to great stability and low offset ultimately translates as high accuracy measurements.
