Type VMN Voltage Monitoring Resistor Networks
Transient Tolerant
New
Voltage Dividers for Industrial Power Quality and Power Consumption Metering Applications
Ratio Tolerance of 0.1% or 0.02%, Ratio TC of 10 ppm/°C or 5 ppm/°C
The Type VMN Transient Tolerant Voltage Monitoring Networks are
designed for use in the voltage measurement circuits of Power Quality
Monitoring Equipment, Kilowatt-Hour Meters, and other Power and Energy
Measurement Equipment, where precision electrical service voltage
monitoring is required.
The VMN Networks are manufactured with Tetrinox®, Caddock’s Ultra-
StableLow-TCResistanceFilmSystem. TheTetrinoxfilmsystem, combined
with Caddock’s Ceramic Sandwich Resistor Network construction, provides
outstanding long-term stability in industrial applications with electrical
surges, transient conditions, and high humidity exposure.

7 Normal Operating Voltage applied to R1 and R2 connected
in series at +85°C. Change in Ratio after 2,000 hours is
±0.02% maximum.
Lead Form Detail Note:
The lead form detail provides
interference in the circuit board
hole to achieve a vertical mount
of the device. Recommended
circuit board hole is nominally

rise time of 1.2 microseconds to 90% of the impulse voltage
peak, followed by a fall time of 50 microseconds to 50% of
the impulse voltage peak. Impulse applied to Pin 1 (with R1
