New Product ~ 1600W Programmable AC/DC Power Supply and Intelligent Charger
Introduction:
RSP series(75-3000W)
After dedicating about a year into the development, integrating the market demands for the “enclosed type” / “rack mountable” power supplies and chargers, MEAN WELL is pleased to unveil four new products all at one time, the 1600W single output programmable power supplies and chargers (or say, the RxP-1600 family), and a new rack shelf:
• RSP-1600— Programmable Enclosed Type Power Supply
• RCP-1600— Programmable Rack Mountable Front End Rectifier
• RPB-1600— Intelligent Battery Charger
• RCB-1600— Rack Mountable Front End Battery Charger
• RHP-1U —1U-high 19” rack shelf (workable with RCP-1600 or RCB-1600)
These four new 1600W power supply and charger series operate for the full range single phase input 90~264VAC, consisting of various models ranging between 12DC and 48VDC, respectively. In addition to the output programmable function, each standard series is equipped with PMBus (exception: optional spec for RSP-1600) and the under-planning CANBus, enabling RSP/RCP-1600 series perform the higher level signal monitor or output read/write function, or permitting the users to flexibly setting up and adjusting the charging curves for RPB/RCB-1600.
With the high power density 25W/inch3 and the highest efficiency up to 93.5%, the main body of the RxP-1600 family is 1U by height and 85mm by width, making them perfectly meet the requirements of the controllability for high wattage power supplies and the trend of miniature for the power supplies and chargers. RSP-1600 and RCP-1600, as well as RPB-1600 and RCB-1600, utilizing the same level circuit design; users can acquire as high as 24000W output according to application environment and the built-in current sharing function. Each model from the RxP-1600 family acquires the major safety certificates in the world, such as UL, CUL, TUV and CE; moreover, 5 year warranty is offered so as to present the best guarantee for safety and reliability.
MEAN WELL programmable power supply and charger series outstandingly fit a variety of applications (for example, aging facility, semiconductor testing instruments), providing the power solution with high stability and high cost-performance ratio for the diversified systems needing output voltage or current adjustable, allowing uses to easily change the output voltage or constant current level by applying external voltage or resistance.
For further information about these four new products, please refer to the following table.
◎1 MEAN WELL will introduce the solution with CANBus. Please contact MEAN WELL for details.
◎2 RHP-1U standard size shelf (365x440x44mm) fits both RCP-1600 and RCB-1600 modules
(one type of product used for one shelf at a time.) One stack of a fully-populated shelf is able to provide
up to 8000W; up to 3 stacks with RCP-1600 are able to operate in parallel to provide up to 24000W
Established in 1982, MEAN WELL Enterprises Co., Ltd. is one of the leading switching power supply providers in the world. MEAN WELL dedicated in developing energy-saving concept products for many years. Since 2006, we started to endeavor the effort to the LED / outdoor power supply development. Thus far, full range of LED power family with more than 1000 models (100 series) from 8W to 600W was launched in the market with utmost success. Most of them are also comply with specific norms of UL8750, EN61347-2-13, IEC61347-2-13(CB), EN61000-3-2 Class C (harmonic current) and IP20~67.
If you are looking for LED power supply with high reliability, good quality, reasonable price and full series products which can satisfy your various demands, MEAN WELL, a total solution provider, is definitely your first choice!
Application Q & A
1.Which model should we select when attempting to dim a LED strip?
Generally speaking, LED strips would be connected with resistors in series, so the LED must be driven in CV mode. We will suggest those models offering CV dimming to be adopted, such as PWM series
2.How can we learn how many units of the model with 3 in 1 dimming can be controlled by one dimming device?
3 in 1 dimming circuit would drain 0.1mA per model. Dividing the rated current of the dimmer by the 0.1mA, and we could know how many units can be controlled by one dimming device. For resistance dimming applications, resistance for 100% dimming output would be 100K ohm divided number of models.
3.There are so many MW dimming products. How can I make a choice? What are the pros and cons?
First, you have to know your Led lamp specification in order to screen out a suitable Led driver range (Wattage, Voltage, Max Current CC or CV). From those ranges, further check a compatible dimming function. Hereunder is a table to show you the pros and cons of Dimming Function you can find in MW’s catalogue.
4.I cannot do dimming with MW LED drivers?? Why?
First, please make sure your LED lamp or modules are Constant Current (CC) driven or Constant Voltage (CV) driven. If you are using CC-driven LED applications, please verify that MW LED driver’s rated current on datasheet can match your LED current requirement. If you are using CV LED applications, we offer PWM series for CV dimming applications.
5.What to consider when selecting LED power supply?
a.Lighting system designed to work in direct drive mode
The combined LED forward voltage range (upper and lower) must fall within LED power supply’s constant current voltage range. For example, the LED Vf spec is 3.4~3.6V, when 6 are connected in series the combined Vf will be 20.4~21.6V. In this case, a 24V unit must be selected with constant current region of 18~24V.Ø
For models with active PFC and system PF requirement is >0.9, load usage must be higher than as specified in the PFC spec. Relationship between PF and output load can be found in figure 1. The typical requirement is 75% load or above. Double check the spec for the model you are using to confirm actual requirement.
In areas with unstable AC voltage such as heavy industrial zone or generator supply utility, please select general usage LED series from table 1.
b.Lighting system designed to work with driver IC
The start up voltage of driver IC should be as close to the power supply rated voltage as possible.
Driver IC needs stable voltage to function properly. So, it is highly recommended to use general usage series from table 1.
For models with active PFC and system PF requirement is >0.9, load usage must be higher than as specified in the PFC spec. Relationship between PF and output load can be found in figure 1. The typical requirement is 75% load or above.
Double check the spec for the model you are using to confirm actual requirement. When using driver IC, possible system EMI issue could arise. After completing lighting system design, EMI must be double checked. For suggestion on system EMI problem solving, refer to question 11.
