| DIGITAL MULTIMETERS DMK 2...- DMK 5... TYPES | |||
|
The DMK 2..., DMK 5..., types give reliable readings and measures even in the most critical conditions such as voltages and currents with high harmonic content and variable frequency. The total and partial hour counter function is an interesting feature for generating set control boards, especially the DMK 25 and DMK26 models with DC auxiliary supply. The variety and accuracy of the measures make these multimeters a winning technical-cost effective substitute to conventional analog measuring instruments. |

| DIGITAL MULTIMETERS DMK 3... - DMK 40 - DMK 6... TYPES | |||
|
The DM 3... - DMK 40 - DMK 6... types comprise excellent features, superior to devices of the same category currently on the marketplace. Distorted waveform conditions, for current and voltage with high harmonic content and variable frequency, do not influence the high accuracy DMK multimeter readouts because of rigorous design in addition to the use of the latest generation of microprocessor technology. Measures of the phase angle (cosphi) as well as power factor, harmonics analysis and HIGH-LOW-MAX functions are just a few of these, which are difficult to find on higher category equipment. The DMK 40 model includes a powerful and easy-to-use data logger along with the other features mentioned above. |

| MODULAR DIGITAL METERING INSTRUMENTS DMK 7... - DMK 8... TYPES | |||
| The modular digital metering instruments DMK7 and DMK8 warrant a extreme stability of the readouts owing to the large number of samplings. The measures in TRMS provide for a correct operation even in presence of voltage and current conditions with high harmonic content. The metering instruments find use in single or three-phase power distribution boards for both industrial and service fields. All the models are able to store and display maximum (HIGH) and minimum (LOW) values of the readouts. There are DMK R1 types available with the same features along with one programmable relay output. Units equipped with a voltage measure input, consent to program the VT (Voltage Transformer) ratio and therefore can be employed in medium-voltage systems. They can be used as an effective solution to replace traditional analog instruments, that is voltmeter and ammeter complete with relative changeover switches, with the advantage of extra panel space. |

| CURRENT TRANSFORMERS DM...T TYPES | |||
| The DM...T types current transformers (CT) are installed in electric systems to reduce the line current to a secondary value of 5A, which is compatible with current inputs of digital multimeters or protection relays. These are without primary winding and are used for high primary current values from 40A up. Suitable for screw fixing or mounting on 35mm DIN rail (EN50022), using the standard-supplied kit. The number of loops of the primary cable does not modify the accuracy but converts the primary current value proportional to secondary current. |
