New Products Introduction Low Power Consumption Fan “San Ace 120” 9GA Type Yasuhiro Maruyama Jane Oliva Rogen Molino Chamir Gallardo Stephen Lloyd Velarde Gerald Manalansan Jan Michael Heramis Michinori Watanabe 1. Introduction The 120 × 120 × 25 mm sized fan is one of the most standard sizes and is used in all kinds of market applications. However, there is an increasing demand from the market for this size fan to achieve even lower power consumption while maintaining a high cooling performance. In response, SANYO DENKI developed and released the “San Ace 120” 9GA type 120 × 120 × 25 mm fan (hereinafter, “new model”) which achieves one of the lowest power consumptions in the industry*. The new model has a newly designed impeller, frame, and motor and maintains compatibility in size, mounting holes, etc. with the current model, the 120 × 120 × 25 mm “San Ace 120” 9GV type fan (hereinafter, “current model”). In the performance aspect, the new model accomplishes high static Fig. 1: 120 x 120 x 25 mm “San Ace 120” 9GA type pressure and low power consumption in the actual operating area. This article provides a detailed introduction of this new product. 3. Product Overview 3.1 Dimensions 2. Product Features Figure 1 shows a photograph of the new model. Figure 2 shows the dimensions of the new model. The new model has the same mounting dimensions as the current model, therefore compatibility is maintained. The features of the new model are as follows: (1) High static pressure (2) PWM speed control function 3.2 Characteristics 3.2.1 General characteristics There are three rated voltages to choose from (12 V, 24 V, (3) Low power consumption 48 V), and each of these offers two rated speeds of either (4) An abundant product lineup 6400 min-1 (G speed), or 5400 min-1 (S speed). Moreover, the lineup features models with a PWM control function The new model features a newly designed impeller, frame, enabling speed variation in accordance with an external and motor and accomplishes high static pressure and low PWM signal, as well as models without the PWM control power consumption in the actual operating area. function capable of supporting a wider operating voltage range. Table 1 and Table 2 show the general characteristics of the models with a PWM function and the models without a PWM function, respectively.
