| ※1 Depends on connection conditions. Also, this does not guarantee repeated switching. We recommend that you confirm operation under actual conditions. ※2 This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the actual load. ※3 When using the lamp control type, please inquire our sales representativ. ※4 The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. |
