30a 500w

12-50V 30A 500W Adjustable Speed Controller DC Brush Motor Speed PWM Controller Adjuster with Control Switch   It's a PWM speed controller so it enables you to control the speed of these little DC brush motors smoothly.  It's ideal for applications like fans, etc. providing nice adjustment of motor speed instead of the more usual "High-Low" switching   Specifications: Operating Voltage: DC 12-50V Rated Current: 30A Control Power: Max. 500W Speed Control Range: 0% -100% PWM Frequency: 21KHz Item Size: 70 * 40 * 30mm Quantity: 1pc   Features: Wide range of operating voltage: 12V 250W, 24V 350W,... 48V 500W A good speed controller for DC brush motors. High-frequency capacitance, power tube and 10A fuse are used in the module. Adopts sealed and high-quality potentiometer with switch, stable performance. Metal case creates better durability; high efficiency and low noise. Suitable for applications like fans, etc. providing nice adjustment of motor speed.   Warning: 1. This speed controller is applicable to DC brush motor, not the DC brushless motor; it can't be used as voltage regulator. 2. It should be connected with DC voltage, don't connect with AC voltage(e.g. 220V AC). 3. It can not use the 48V battery, battery power supply (48V storage electrical voltage of more than 50V.) 4. The anode and the cathode of DC power cannot be connected reversely, otherwise the controller will be damaged. 5. When running direction is inconsistent with your desire, you can change it by adjusting the linear order. 6. Potentiometer switch can change the output duty cycle of controller and then change the motor speed.   Package Includes: 1 *  DC Motor Speed Controller   More Details:

The SPS is an all-in-one uninterruptable power supply (UPS) for home or business. It can be used straight out of the box and does not require an electrician. Simply plug the unit in to a standard wall socket (cable supplied), plug your TV, DSTV, computer, lights etc. into the SPS and you will have uninterrupted power. In the event of a power failure the unit automatically takes over. Your appliances keep working. When power is restored it switches back and recharges. Available in three sizes priced from R2,950: SPS-500 800VA (500W), SPS-600 1KVA (600W) and SPS-1000 1.5KVA (1000W). The SPS-1000 and SPS-600 include a built in solar controller for optional connection to a solar panel. Simple operation. Fully automatic. Uninterrupted power (UPS). Long back up time. Professional, all-in-one cabinet. Pure Sine Wave. Solar controller on SPS-600 and SPS-1000. 3 stage battery charger. 15A - 30A charging. Intelligent CPU control. Automatic Voltage Regulation. LCD Information display- battery charge, input/output voltage. Re-settable overload protection. Low battery/overload warning. 2 x Peak Surge capacity. Portable - on wheels. No exposed wiring. Lockable battery compartment. Fan cooling. 12 Months warranty. Full details on our website www.smartpowersystems.co.za The SPS is priced with and without batteries in case you already have batteries or want to source them elsewhere. The battery is an essential component of any power system. The SPS can operate with all deep cycle battery types, however we only supply GEL CELL batteries. Their thick plate electrodes and gel electrolyte give them a cycle life twice that of standard deep cycle batteries and the capability to be deeply discharged and to repeatedly accept recharging. SPS-500 800VA (500W) excluding batteries R2,950. Including 1 x 100Ah GEL battery R4,950. SPS-600 1000VA (600W) excluding batteries R3,950. Including 1 x 100AH GEL battery R5,950. Including 2 x 100AH GEL batteries R7,950. SPS-1000 1500VA (1000W) excluding batteries R4,950. Including 2 x 100AH GEL batteries R8,950. Prices quoted are what you pay. No VAT on top. Safe courier delivery throughout SA with insurance and tracking from R260. If you want to see the SPS in operation we have the machines on display in West Beach. Or if you are in the Cape Town area and want a no obligation demonstration we can bring one to you. There is a wealth of inverter and battery information on the internet but if you need advice, or want to know which SPS best suits your needs, we are happy to help. www.smartpowersystems.co.za

The SPS can be used straight out of the box and does not require an electrician. You simply plug the unit in to a standard wall socket (cable supplied), plug your TV, DSTV, computer, lights etc. into the SPS and you have uninterrupted power. During load shedding the unit automatically switches to battery power. Your appliances keep working. When power is restored it switches back and recharges. Available in three sizes: SPS-500 800VA (500W), SPS-600 1KVA (600W) and SPS-1000 1.5KVA (1000W). Details on our website www.smartpowersystems.co.za Priced from R2,950. The SPS-600 and SPS-1000 include a built in solar controller giving the added option of connecting to a solar panel at any time. Simple operation. Fully automatic. Uninterrupted power (UPS). Long back up time. Professional, all-in-one cabinet. Pure Sine Wave. Solar controller on SPS-600 and SPS-1000. 3 stage battery charger. 15A - 30A charging. Intelligent CPU control.

The SPS range is priced with or without batteries in case you already have batteries or want to source them elsewhere. The battery is an essential component of any power system. It will determine how long the system will run, how deep you can drain the battery and how many times you can discharge it (cycle life). The SPS can use any deep cycle battery type, but NOT a car battery (see faq's on our website for details). The batteries we supply with the SPS are GEL cell. They are safe, spill proof and leak proof with the capability to be deeply discharged and to repeatedly accept recharging. Thick-plate electrodes and gel electrolyte give them a cycle life twice that of other deep cycle batteries. SPS-500 800VA (500W) excluding batteries R2950. Including 100Ah GEL battery R4950. SPS-600 1000VA (600W) excluding batteries R3,950. Including 100AH GEL battery R5,950. SPS-1000 1500VA (1000W) excluding batteries R4,950. Including 2 100AH GEL batteries R8,950.
