ESP SL Series NEW
TSC-0912 - 09.10.12
Technical specification
The ESP SL ‘Slim Line’ Series is also available for protection of 3-wire, RS 485 and RTD applications (ESP SL/3W, ESP SL RS485 & ESP SL RTD).
The ESP SL X Series has approvals for use in hazardous areas.
1 Nominal voltage (DC or AC peak) measured at < 10 µA
(ESP SL15, ESP SL30, ESP SL50, ESP SL110 and LED variants)
and < 200 µA (ESP SL06 and ESP SL06L).
2 Maximum working voltage (DC or AC peak) measured at
< 1 mA leakage.
3 The maximum transient voltage let-through of the protector
throughout the test (±10%), line to line & line to earth, both
polarities. Response time < 10 ns.
4 Test to IEC 61000-4-5:2006, ITU-T (formerly CCITT) K.20,
K.21 and K.45, Telcordia GR-1089-CORE, Issue 2:2002,
ANSI TIA/EIA/IS-968-A:2002 (formerly FCC Part 68).
