Product catalog summary
Specifications:
The document outlines the specifications for hydraulic power packs, including insulation class 'F' as per VDE 0580, a protection class of IP 65 according to DIN 40050, and a voltage tolerance of ±10%. The ambient temperature range is specified as -15°C to +40°C, with power consumption details provided for both DC (18 W) and AC (28 V.A. holding, 40 V.A. in rush) operations. The maximum operating pressure is 210 bar, with a maximum flow of 22 l/min and leakage at 12 cc/h at 210 bar. Response times are 40 msec for opening and 130 msec for closing.
Procedures:
Installation guidelines emphasize the importance of selecting appropriate power packs based on pump displacement and reservoir capacity. The document advises on mounting positions, recommending vibration dampers for installations on vibrating structures. It also highlights the need for proper hydraulic fluid selection and system cleaning.
Standards and Recommendations:
The document references several standards, including VDE 0110 for insulation and DIN 51524 for hydraulic fluids. It recommends filtering hydraulic fluids before use and maintaining a working temperature of 60°C, with a maximum of 80°C. The document also provides guidelines for calculating theoretical power requirements and emphasizes the importance of avoiding cold starts under load.
Technical Features:
The power packs are designed for modularity, allowing for easy interchangeability of components. This design provides flexibility and economic efficiency in stocking components. The document details the technical features of pumps, including displacement, maximum speed, and pressure ratings. It also covers the specifications of electric motors, including power, size, and mounting positions.
Maintenance:
Regular maintenance is advised, including frequent cleaning of the hydraulic circuit and replacement of hydraulic fluids. The document outlines the service limits of DC electric motors, providing formulas for calculating service limits and working time.

BREVINIMotion Systems CENTRALINA POWER PACK MR Le centraline serie MR sono state concepite per offrire una soluzione razionale ed economica ai piu svariati problemi di automazione oleodinamica. La modularity e realizzata attraverso componenti standardizzati di larga produzione che uniscono un elevato livello qualitativo ad un'estrema semplicita di assemblaggio e di funzionamento. Questi componenti sonofacilmente intercambiabili e dannoallecentraline una eccezionaleflessibilita di impiego per le piu svariate esigenze. La modularity consente inoltre di avere a disposizione l'intera gamma di centraline con uno stoccaggio versatile ed estremamente economico di componenti. Ne deriva un gruppo compatto con elevate prestazioni e silenziosita, la cui economicita di esercizio ne consente l'impiego in tutti i settori industriali. The MR power packs have been studied to offer a rational and economic solution to the many applications of the hydraulic automation. The modularity is realized with large production standard componentsjoining a high quality level to a very simple way of mounting and working of the unit. The components are easily interchangeable and make powerpacks exceptionallyflexible. More on, the modularityallows the availability of the whole range of power packs with a versatile and economic stocking ofthe components. The result is a compact, economic and noiseless unit with high performances to be employed in all the industrial fields.
