Detailed Technical Analysis
This high voltage board monitors three independent DC bus voltage points. It scales voltages from 0 to 1000V DC down to 0 to 10V outputs. The high input impedance of 5 megohms loads the measured circuit minimally. A 100:1 scaling ratio provides safe signals for control circuits.
Now let us examine its isolation features. This board provides 3500V RMS isolation between input and output circuits. Approximately 110 components populate both sides of this 6-layer PCB. Twelve integrated circuits include isolation amplifiers and operational amplifiers. Six electrolytic capacitors filter the power supply for stable operation.
This high voltage board draws 140 milliamps from a 24V DC external supply. A single green LED confirms that power is present. Six gold-plated test points allow voltage verification during commissioning. The GE DS200SHVIG1B DS200SHVIG1BGD achieves ±0.3% accuracy across the full input range.
Installation and Connection Guidelines
You mount this board using four M4 screws with insulating standoffs. Connect the 24V DC power supply to the designated terminal block. Wire the high voltage inputs to the terminal block with proper insulation. Use wire rated for the maximum input voltage of 1000V DC.
Always discharge the DC bus capacitors before connecting or removing this board. High voltages can remain present even after power-down. Verify output scaling with a calibrated voltmeter before use. The board automatically scales the input signal upon power-up.
Practical Applications
Engineers use this high voltage board for drive voltage monitoring and protection. It provides safe feedback for DC bus regulation loops. This component also works in legacy drive upgrade projects. Its three channels suit three-phase drive bus monitoring applications.
Summary of Features
To conclude, this high voltage board scales 1000V DC down to 10V DC outputs. It weighs 0.42 kilograms and provides 3500V RMS isolation. Choose DS200SHVIG1B DS200SHVIG1BGD for reliable voltage monitoring in drive systems.
