Đồng hồ đo tốc độ, tần số: TDS – K0821
Thông số kỹ thuật :
- Measuring signal input: generator residual voltage or PT frequency;
- Measuring range: 0.1~100 Hz (generator frequency);
- Input voltage: generator residual voltage or PT signal 2.0~250VAC;
- Measuring accuracy: 0.1%±1 character;
- Digital display content: speed, frequency, percentage value and percentage Max. value.
- 5-channel, 6-channel, 7-channel, 8-channel, 9-channel, 10-channel speed control setting: the setting value of each channel can be set within 1% Ne to 200% Ne, but pay attention to the generator characteristic. （8-channel as an example in the following table） each point of central speeds of 5% Ne, 35% Ne, 80% Ne, 90% Ne, 95% Ne, 99% Ne, 115% Ne, 140%Ne（adjustable） can be set by the Customer within the specified range.
- Input contact capacity: 1A/220VAC 1A/220VDC；
- Maximum value memory: can memorize and indicate the maximum vaules of speed, percentage and frequency. The customer can clear(within 100Hz);
- Simulation signal output: 4~20mA, RS485（related to 0%~200%Ne of the unit’s speed）;
- Ambient: temperature 0~40℃;
- Power source: DC or AC110V~220V;
- Power loss: within 15W;
