AC Speed Controller  Rotational speed N of an induction motor can be shown by the expression (1). When the voltage applied to the motor is increased and decreased, the slip s changes, then the rotational speed N will change N= 120·f ·(1-s)/P · · · · · · · · · · (1) N: Rotational speed [r/min] F: Frequency Hz P: Number of poles of a motor S: Slip In the case of an induction motor as shown in Fig. 4, a stable range and an unstable range exists in the Rotational Speed - Torque curve. Since it is impossible to reliably operate in the unstable range, simple voltage control (open loop control) is limited to controlling the speed in a narrow range like, N1~N3 in Fig. 5. To make it possible to operate reliably even in the above-mentioned unstable range, it is necessary to detect the rotational speed of the motor and use a voltage control mechanism (closed-loop control) that reduces the speed error when compared to a set value.

Ac motor + pump: high life cycle pump with high efficiency and better discharge. Solar ac pump controller: transformer less high efficient and micro controller based pump inverter. Module mounting structure: galvanized iron mounting structure with dual axis manualauto tracking facilities for long time operation in a day. Accessories: cable, connectors, pipe and other accessories. Note: for best competitive solution for your required solar water pumping system following details should be given. Pump setting depth (in metersfeet). Requirement of daily water (in littersgallon). Site location of solar water pumps installation. Advantages irrigation possible at remote locations environment friendly operations conventional grid electricity is not required highly reliable and durable ac high efficient motor + pump eco-friendly (zero noise pollution -zero co2 emission ) complete independence from grid connection for water supply 25 years power output warranty on the solar panels no fuel required almost no maintenance required provide consistent water solar pv arrayit consists of an array of solar panels connected in series and parallel combination to achieve the desired voltage and current necessary to drive the ac pump. The power rating of the solar array will be suitable to the design of the pump. Conventional ac 3 phase motor & pumpac pumps are conventional pumps that are currently in use across the world for various applications. Currently these pumps run on ac power from the grid (batter overall efficiency of the pumpset will lead to reduce the number of solar panel) solar ac pump controller with inbuilt mppt function (solar ac pump inverter)a transformer less inverter system, 415 vac 3-phase output voltage and vf control to manage pump starting condition (soft start). The equipment is micro controller based and operated with software for digital control of inverter parameters, fault finding diagnostics and digital io signalling. With the inbuilt mppt (maximum power point tracking) function, it regulates the output frequency according to irradiation in real time to achieve the maximum power. Adopting the proposed dynamic vi maximum power point tracking (mppt) control method, fast response and stable operation can be possible, better than the conventional methods, it can overcome the problems including poor tracking performance, unstable or even cause water hammer damaging when the irradiation on the array changes rapidly. Mounting structure galvanized iron dual axis manual tracking structure will ensure the long time hassle free operation. Optionally we will provide auto tracking or fix tilt tracking. Accessories hdpegi isi standard pipe for higher strength and easy installation with higher life expectation. Isi standard copper cable to ensure fire proof operation.

This product is designed to control two Air Conditioners(A.C. or A/C) simultaneously. The industry standard AVR Micro-Controller is the heart of this system. Control over the A/Cs are performed according to some parameters like temperature, phase voltage, phase current, swapping time etc. User can set or view various parameters like current temperature, phase current, phase voltage, temperature set-point, high room temperature, swapping time, A/C trip current, A.C. last trip reason etc. through a 16 x 2 character LCD panel and a status indication panel will help user quickly monitor the status of the A/Cs. An alarm system generates respective alarm for FMC if any error occurs in the operation. This system keeps the information of last AC trip reason and the overload current at which the Air Conditioner (A.C.) was last tripped in a nonvolatile memory for up to 100 years or the next trip occurs. This devise is fully compatible with VOLTAS SENSICOOL Air Conditioners (A/Cs) used in the shelter of a mobile tower.  Where to buy
