The intelligent and space-saving integration of the fan in the device configuration is therefore of major importance: • Tailor-made cooling adapted to the situation as and when required. • Programmable cooling by defining speed profiles. • Transparency of function thanks to complete, interactive monitoring in all operating conditions. Standard fans in electronics cooling have proven themselves millions of times. With a constant speed and a correspondingly high noise level, they continuously provide the air flow needed for extreme cases. These extreme situations, however, occur extremely rarely, if at all, during the operating period. An intelligent fan is needed, which adapts automatically to the currently required level of cooling. 2016-01 ebm-papst provides intelligent cooling concepts which are optimally adapted to requirements. For example: 166 1. Speed adjustment via temperature sensor ebm-papst answers with a complete range of DC fans with temperaturecontrolled speed adjustment via a temperature sensor, available in a variety of standard dimensions. Installation is very simple. The control electronics receive thermal information for the speed adjustment continuously and without losses, either externally via a freely designed and positionable strand, or internally directly in the fan hub in the air flow. A range of temperature sensors can be found on page 178. 2. DC fans with separate control input Open or closed-loop speed control is also possible with DC fans that have a separate control input. A variation in speed can thus be implemented via a control voltage or a pulse-width modulated signal. These possibilities are used primarily in devices that have appropriate standard interfaces and thus require a load-dependent variation of the fans. Information DC centrifugal fans DC axial fans DC fans - specials ACmaxx / EC fans AC axial fans AC centrifugal fans 7. Protection against environmental influences Some applications place particular demands on the fans resistance to ambient influences, such as dust, moisture, water and salt. ebm-papst offer solutions for adapting fans to these ambient conditions. Accessories 5. Turbo drives Fans with three-phase EC drives and microprocessor-controlled motor electronics. These three-phase motors whose torque is virtually nonreliant on the rotor position are used for extremely high running smoothness. The speed of these fans can be controlled over a very wide range with PWM, analog voltage or temperature. Optionally, the fans can be supplied with reversible direction of rotation and active brake operation. The successful concept of Vario-Pro is: Tailor-made software instead of fixed hardware, because programmed software modules for motor control and application intelligence are responsible for the work that analog components were responsible for in the past. This central control unit of the Vario-Pro comprises a microcontroller and an EEPROM, on which all characteristics are stored. 167 Representatives 4. Alarm signal For applications which require monitored fan operation with alarm signal, ebm-papst has numerous alarm signal versions, either a static, pre-processed or interface-compatible high or low continuous signal depending on the type of fan. 6. Vario-Pro fans This high-end fan concept by ebmpapst with programmed intelligence and customer-specific integrated functions makes your electronics cooling even more versatile and competitive. Vario-Pro ensures a fresh economic breeze for all demanding cooling tasks – e.g. where greater reliability, more flexibility and intelligent function features such as alarm function, speed control etc. are required. 2016-01 3. Speed signal DC fans with speed signal. The integrated „electronic tachometer“ continuously provides an actual speed signal for external evaluation. The user is informed at all times of the current fan speed via an extremely simple signal evaluation on the customer side. The speed signal is via a separate lead.

The degree of protection IP 68 is important for ebm-papst products, as it ensures a high degree of protection for the encapsulated motor and electronic against foreign bodies and water, whilst protecting the user against potential hazards upon contact. Degree of protections higher than IP 68 are possible upon request. Salt fog protection Salt fog is extremely demanding on the resistance of the product. ebm-papst makes use of technologies that protect fans and blowers from salt fog reliably and durably. Stainless steel bearings Special bearings made of stainless steel provide additional protection. ACmaxx / EC fans Moisture protection Coated motor and printed circuit board protects against humidity and condensation.
