Criteria A Radiated Immunity EN61000-4-3 10 V/m Perf. Criteria A Fast Transient (See Note 5) EN61000-4-4 ±2kV Perf. Criteria A Surge (See Note 5) EN61000-4-5 ±1kV Perf. Criteria A Conducted Immunity EN61000-4-6 10 Vrms Perf. Criteria A NOTES 1. Heat sink is optional. To order the module with a heatsink please add the suffix “HS” to the model number (Ex: CBW24S12-2500HS). 2. Positive remote on/off control is standard; for negative remote on/off please add the suffix “R” to the model number (Ex: CBW24S12- 2500R). 3. Triple output models require a minimum loading on the output to maintain all specified regulations. Operation under no-load conditions will not damage these devices; however, they may not meet all listed specifications. 4. The CBW series standard models can only meet EN55022 Class A and Class B with external components added. 5. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. - 24VDC nominal input models: Nippon chemi- con KY series, 330μF/50V - 48VDC nominal input models: Nippon chemi- con KY series, 220μF/100V CAUTION: This power converter is not internally fused. An input line fuse must always be used. Due to advances in technology, specifications subject to change without notice. |
