Technical Specifications

The document provides detailed electrical and mechanical specifications for the ECP 34 series of industrial electrical machines, likely alternators or generators, manufactured by MECCALTE spa. Key electrical parameters include operating frequencies of 50 Hz and 60 Hz, with voltage ratings at 400 V, 415 V, 440 V, 460 V, 480 V, and associated configurations such as Series Star (Y), Parallel Star (YY), Series Delta, and Parallel Delta connections.

Power ratings (KVA) are specified with temperature rise classes CL. H (125°C) and CL. F (105°C), indicating insulation class and thermal limits. Efficiency (η %) values are provided for different temperature classes and ambient conditions (e.g., 40°C ambient). The machines are designed for 3-phase continuous operation with a power factor of 0.8.

Performance Parameters

Performance data includes airflow volumes (m3/min) at 50 Hz and 60 Hz, noise levels in dB(A), and weight measurements for different models (ECP 34-1S/2, ECP 34-2S/2, ECP 34-1L/2, ECP 34-2L/2). Temperature rise ratings are given for various ambient temperatures (27°C and 40°C) and insulation classes, indicating thermal performance under different operating conditions.

Mechanical Dimensions and Mounting

Mechanical dimensions are detailed for different frame forms (B3-B14 and MD35), including overall sizes in millimeters for each model variant. The document also specifies disc coupling dimensions (length, diameter, number of holes) and flange dimensions (diameter, bolt circle, number of holes) for mounting and mechanical integration.

Protection and Accessories

Protection classes include IP21, IP23, and IP45, indicating degrees of ingress protection against dust and water. Thermal protection devices such as PTC and PT100 sensors, heaters, and bimetallic devices (DSR BIMET) are listed as standard or optional accessories. A regulator device (UVR6) is also mentioned.

Standards and Ratings

The document references industrial and standby ratings for the equipment, highlighting continuous duty capabilities and thermal limits. Noise and airflow data support compliance with operational standards for industrial environments.
