SIPOS 5 Flash Electric Actuators Technology Product range Mechanical interface

Product range Mechanical interface SIPOS 5 Flash Features and benets at a glance Output torque and speed are independent of the supply voltage / frequency (within a wide tolerance) Actuator torque and positioning speed are unaffected by voltage variations of ±15 % of the specified voltage range (transitional voltage tolerance ±20 %) and frequency variations from 40 Hz to 70 Hz. Low starting current – always below nominal rated current Allows lower cable rating / longer cable lengths More actuators can be connected to a given cable size UPS systems can be specified with a lower power rating...

SIPOS 5 Flash Setting new generation actuator standards Over a number of years there has been an increasing trend in process automation to distribute control system functionality away from central control to actual field devices close to point of application. SIPOS 5 Flash actuators are setting the standard in pioneering product development that supports this change. Wide ranging actuator applications The SIPOS 5 Flash actuator series has proven field reliability and constant further development has opened up a wide variety of applications including: – The energy sector – from the power...

Product range Mechanical interface Integrating power and control circuits within the actuator, means components traditionally mounted in separate control cabinets such as circuit breakers, reversing contactors and thyristors have been designed out, thus resulting in lower system costs, simplied installation and increased reliability. Flexible electronics also enables the actuators to be used with both conventional and eldbus systems – the SIPOS 5 Flash is extremely adaptable to the respective control system. The modular structure of the SIPOS 5 Flash allows it to be upgraded from simple...

SIPOS 5 Flash One for all The intelligent approach to actuator design Modern process engineering requires valves which will operate at precisely defined speeds. The SIPOS 5 Flash actuator range incorporates an electronic frequency converter driving a robust induction motor (instead of the conventional motor plus reduction gear arrangement) which allows software congurable speed control (ratio 1:8) for valve open/closure rates. Changing speeds rates is therefore an extremely simple procedure either at time of valve specification or later on-site. Electronics replaces mechanical components...

Control and regulation Suitable for every process SIPOS 5 Flash actuators are available both as standard and modulating actuators. The standard actuators are designed for S2 duty cycles (short-time duty) 15 min, the modulating actuators are designed for S4/S5 intermittent operation with a minimum of 25 % relative duty to a maximum of 1200 cycles per hour in accordance with DIN EN 60034. Two electronics variants SIPOS 5 Flash actuators can be supplied with two different electronic versions: ECOTRON and PROFITRON. Common features • Integrated frequency converter • Electronically adjustable...

SIPOS 5 Flash Mechanical interfaces for all valve types The output shaft for rotary actuators is designed as hollow B1-/B shaft. The torque is transmitted to the valve via a featherkey. Other output shaft forms are achieved by means of inserts or extension modules. Various forms of mechanical interfaces are available which can be used to connect the actuator to different control elements (valves, butterfly valves, gate valves, ball valves). Rotary actuators can be supplied with flange connections and couplings in accordance with DIN ISO 5210 and DIN 3338 or DIN 3210 with output shaft forms...

Mechanical interface Large torque capability Large torque ranges for rotary movements, linear actuators and part-turn actuators are created by fitting precisely matched mechanical components to the rotary actuators. These components continue the concept of modularity seen with the electronics units through the mechanical design of the actuator, thus keeping spare part inventory to a minimum. There are three completely interchangeable gearbox options which are described below: Worm gearbox for direct mounting and worm gearbox with base and lever 2SC5... part-turn actuator Part-turn actuators...

Flexible control by means of a frequency converter Using a frequency converter in the actuator allows complete control of the motor i.e.: speed and direction of rotation together with torque. The voltage applied to the motor by the frequency converter determines the output torque, whilst the frequency determines the output speed. A number of benets offered by this unique combination of frequency converter and controller specially designed for service in electrical actuators includes: – Voltage variation compensation Actuator designed for “80 % nominal voltage”, valve design for torque at...

Product range Mechanical interface The frequency converter – How it works Frequency converters with a DC voltage link are now standard devices employed by a wide range of industry users. The frequency converter generates a three-phase voltage of variable frequency and amplitude from a single-phase or three-phase voltage with a fixed frequency (e.g. 50 Hz) and amplitude (e.g. 400 V). The following is a brief description of how these devices function: 1. Rectification The single-phase or three-phase alternating voltage is rectified by means of a diode bridge: The voltage is smoothed in the...
