K8AB-VS
85% to 110% of power supply voltage
50/60 Hz ±5 Hz
DC input or AC input (40 to 500 Hz)
Continuous input: 115% of maximum input, 10 s max.: 125% of maximum input
Set value ±10% full scale
Set value ± 0.5 s
Operating value ±2%
Error calculation: Error = ((Maximum operating value − Minimum operating value (over 10 operations))/2)/
Average value × 100%
Reset value ±2%
Error calculation: Error = ((Maximum reset value − Minimum reset value (over 10 resets))/2)/Average value
× 100%
Operating time repeat error: ±50 ms
Overvoltage:
Measured when input suddenly changes from 0% to 120% of setting.
Undervoltage:
Measured when input suddenly changes from 120% to 0% of setting.
Power ON lock time repeat error: ±0.5 s
(The operating time when the operating time is set to the minimum value and the power supply suddenly
changes from 0% to 100%.)
Operating value
Drift based on measured value at standard temperature:
−20°C to standard temperature: ±1,000 ppm/°C max.
Standard temperature to 60°C: ±1,000 ppm/°C max.
(Humidity: 25% to 80%)
Operating time
Fluctuation based on measured value at standard temperature:
−20°C to standard temperature: ±10% max.
Standard temperature to 60°C: ±10% max.
(Humidity: 25% to 80%)
Operating value
Based on ambient humidity of 65%
25% to 80%: ±5% max.
Operating time
Based on ambient room humidity
25% to 80%: ±10% max.
Operating value: ±5% max.
Operating time: ±10% max.
Note: The error in the operating value and operating time under standard conditions.
Operating value: ±5% max. (at 45 to 65 Hz)
Operating time: ±10% max. (at 45 to 65 Hz)
Note: The error in the operating value and operating time under standard conditions.
At 40 to 500 Hz
Operating value ±5% max.
Operating time ±10% max.
Note: The error in the operating value and operating time under standard conditions.
