Megohmmeter М1623.1

M1623.1 megohmmeter of in-depth mounting, panel board, vibration-resistant and vibration-resistant, is designed for continuous measurement of the insulation resistance of AC networks under voltage, including those having a galvanic connection with the AC network through semiconductor rectifiers, as well as measuring the insulation resistance of dead DC networks and alternating current. The M1623.1 megohmmeter is used to measure the insulation resistance of AC networks that are energized and do not have a galvanic connection to the DC network, as well as de-energized DC and AC networks. The devices are vibration-proof and shock-proof, made in splash-proof housings. IP 54. Rated voltage 127, 220 or 380 V. Rated frequency 50 - 500 Hz. Accuracy class 2.5. Megohmmeter М1623.1 technical data Overall dimensions of the indicating device - 120 × 120 × 126 mm. Measurement range - from 0 to 5 MΩ. The maximum permissible basic error in the measurement range of the scale length is ± 2.5%. Internal resistance - not less than 240 kOhm. The time for establishing the operating mode is 15 minutes Time to establish readings - 3 s. Scale length - 180 mm. Scale angle - 230º. The limit of additional permissible error caused by a change in ambient temperature from normal + 20 ± 5 ° C to a temperature in the range from -40 ° C to + 50 ° C for devices for every 10 ° C of temperature change is 50% of the designation of the accuracy class. The limit of the additional permissible error М1623, caused by a change in the supply voltage by ± 15% of the nominal, is equal to the limit of the permissible basic error. The limit of permissible additional error caused by a change in the operating position (tilt) of the device from the normal in any direction by 45º - ± 1.25% of the scale length. The limit of permissible additional error and half of the pointer oscillation range when exposed to one-component vibration in the frequency range from 1 Hz to 60 Hz at a maximum acceleration of 19.6 m / s2 is ± 2.5% of the scale length. Isolation test voltage between electrical circuits and the case, as well as between the supply and measurement circuits - 2 kV. Insulation resistance of electrical circuits relative to the case, as well as between circuits for the M1623.1 megohmmeter - at least 20 megohms The warranty period is 2 years. The overall average service life is 20 years. MTBF - not less than 24,000 hours. Parameters of the monitored network: - voltage of the monitored network - 127 V; 220 V; 380 V; - nominal frequencies - 50 Hz; 400 Hz. The overall dimensions of the additional device are 110 × 168 × 95 mm. Weight: - indicating device - no more than 1.3 kg; - additional device - no more than 2 kg.
