说明

JW050A

、JW075A、 The JW100A and JW150A power modules are 36 to 75 volt DC power through the input DC-DC converter voltage range, and provide accurate adjustment DC output. The output is completely isolated from the input end, allowing multiple polarity configuration and grounding connection. The maximum rated power of the module is from 50 watts to 150 watts, and the typical full load efficiency is 84%. The sealing module provides a metal substrate with excellent thermal performance. Provide threaded holes for easy installation or adding radiator for high -temperature applications. Standard function sets include remote sensing, fine -tuning and remote opening/levels, which are convenient and flexibly applied to distributed power. Absolute maximum rated value

Integration consideration

Note: There is no internal fuse in this power module. Must always use the input wire fuse. This packaging power module can be used for a variety of applications, from simple stand -alone operations to the integrated part of complex power architecture. In order to maintain the maximum flexibility, it does not include internal fuses; however, in order to achieve the maximum security and system protection, please always use the input wire fuse. This security agency needs a normal fuse with a maximum rated current of

20A

(see Safety Precautions 1). According to the information provided in this data table, the energy of the excitation rush flow and the maximum DC input current, the same available fuses with lower fixed values can be used. Feature curve

The following figure provides a typical feature of the power module. The numbers of the two switches are the same configuration.

] Input source impedance

The power module shall be connected to the AC impedance input source. High -sensing source impedance can affect the stability of the power module. For the test configuration in FIG. 17, 33 μF electrolytic capacitors (at 100 kHz ESR LT; 0.7Ω) are installed near the power module to help ensure the stability of the device. For other high -induced sources, please consult the factory to further apply the guidance policy.

Safety precautions

For the system approved by the security institution, when using the power module, the power module must be installed at the distance and spacing of the final use of the safety institution standard. , CSA C22.2 number 950-95 and VDE 0805 (EN60950, IEC950). If the input source is not SELV (ELV or the hazard voltage is greater than 60 volts and less than or equal to 75 VDC), the module output shall meet the safety and low voltage requirements (SELV). Voltage insulation, including AC power. A VI pin and a VO pin are grounded or input and output pins at the same time should be kept floating. The input pin of the module cannot be accessed by the operator. Throughout the system, in accordance with the requirements of the security agency, the binding module of the supply source and the subject is verified by a single failure, and the output end of the hazard module does not have voltage. Note: Do not output the module that is not groundedOne of the feet. This may cause non -SELV voltage between the output pin and ground. The power module has an ultra -low voltage (ELV) output when all inputs are ELV. The input of these devices should be equipped with a normal melting fuse of 20 A on the unrestrained wire.

Feature description

Over current protection

In order to provide protection in the case of failure (output overload), the device is equipped limit. At the current restriction, the unit switch from voltage control to current control. If the output voltage is pulled very low when the severe failure, the current limiting circuit can show the characteristics of folding or too small (the output current decreases or increases). Once the output current is brought back to the specified range. Remote opening/level offers two remote opening/level options. Positive logic remotely open/control the voltage of the module on/off the feet during the logic high level. Negative logic remote open/off the logic high -power closure of the module, and it usually opens in the logic low. The logical logic (code suffix 1 ") is the preferred configuration of the factory. To open and turn off the power module
