UB2-3NU-L

The UB2-3NU-L is one member of the UB2 series.NEC's UB2 relay is a new generation Miniature Signal Relay of super-compact size and slim-pakage.But, the latching type production is going to start after June 2000.While NEC Corporation has been making continuous effort to enhance the reliability of UB2-3NU-L's electronic components, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC electronic component, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features.

Features of the UB2-3NU-L are:(1)small mounting size of slim package for dense mounting; (2)bellcore (2500V) and FCC (1500V) surge capability; (3)IEC950/UL1950/EN60950 spacing and high breakdown voltage(basic insulation class on 200V working voltage); (4)low power consumption 140 mW.The latch type relay should be initialized at the appointed position (set or reset position) when using, and should be energized or deenergized to the specified polarity to avoid wrong operations by reversed contact state.

The absolute maximum ratings of the UB2-3NU-L can be summarized as:(1)ambient temperature:-40 to 85;(2)coil temperature rise:18 degrees at nominal coil voltage (140 mW);(3)nominal operating power non-latch type:140 to 230mW.No part of this document may be copied or reproduced in any form or by any means without the prior written consent of NEC Corporation.
