1 Hydraulic ini ower ack S 5 Example: plastic tank version Q max 17 l/min p max 25 bar max 3 kw echnical Features C and DC electro-hydraulic unit, easy-to-assemble, compact odularity offers many combinations of hydraulic circuits to suit various requirements ain applications are fork lifts, lifting platforms, automotive lifts, cranes for small trucks, snow plows, machine tools, food and textile industry 7 central block basic circuits options ossibility of building up an additional circuit in the form of vertical or horizontal stacking assembly Rated power up to 3 kw with DC and C Single and triple-phase motors with power ratings of up to 3 kw ank capacities from 1.5 to l with optional plastic tanks for cost saving In the standard version, the aluminium basic block is without surface protection and steel plate are zinc coated for 2 h protection acc. to ISO 9227 Example: steel tank version Functional Description Compact mini hydraulic power packs are designed to fit small design envelopes and can be used in lifting platforms, elevating tables, manipulators, small presses, machine tools and mobile applications. Each power pack consists of an electric motor, a pump, a manifold and a tank. he aluminum body forms the base of the power pack, on which all the main components, including the hydraulic elements, are mounted. he function of the power packs is apparent from the respective hydraulic circuit diagrams. he desired combination of particular components and hydraulic elements can be defined by reference to the ordering code and the respective tables. he additional hydraulic circuits can be built up in valve sizes 3 (REK), (CEO 2) and 6 (CEO 3). he size 3 (REK) is in a form of sectional directional valves. he mounting position of the power pack is horizontal or vertical - see ower ack Dimensions on pages to 19. ll ports have G1/ internal threads (thread G3/8 to be agreed with the manufacturer). With the standard model, the connecting ports, of the components of the vertical stacking assembly are oriented to one side. Orientation of ports, to different sides is to be discussed with the manufacturer. he basic combinations of electric motors and pumps as well as their code designations are shown in tables 1-5. echnical Data Flow rate l/min see table 1, 2, 3, and 5 Working pressure bar see table 1, 2, 3, and 5 ax. operating pressure bar see table 1, 2, 3 and ank capacity l ype of hydraulic pump gear pump, COUNER-CLOCKWISE Electrical otor power ratings kw. - 3 ype of electric motor one-, three-phase and DC Voltage of electric motor V 23 C 23 / C / 2 DC Duty cycle S3 of electric motor % C 1, DC see table Frequency Hz C 5 rotection degree of electric motor - insulation class C I 55-F, DC - see table (page 7) Viscosity range mm 2 /s Fluid temperature range C Fluid temperature range, short-time C mbient temperature max.

Duty S2 (min) - short-time operation he motor operates with constant load for a definite time until the motor reaches the maximum permissible temperature max. It is followed by an idle period long enough to reach equality between motor temperature and ambient temperature. Duty S3 (% ED) - periodic operation he operation of the motor is a continuous sequence of identical cycles, each compound from a load period and an idle period. During the load period the motor can reach the maximum permissible temperature. S3 value shows, in percentage, the length of the load period with respect to the total cycle-load period more idle period. he S3 curve quoted in the performance specifications is referred to a lenghts cycle of 1 minutes. age 1 Subject to change S 5_72_1en_2/216
