CUSTOM SPECIFICATION : OPTION /X2

Major specification changes

Input span: 10 - 50 % of input span of std. input range

MODEL: LTWT–[1][2][3][4][5]–[6][7]/X2

Same as standard specification (without customization)

except followings.

Refer to standard specification pages.

ORDERING INFORMATION

• Code number: LTWT–[1][2][3][4][5]–[6][7]/X2

For each of [1] through [7] same code as standard

specification is available.

Use Ordering Information Sheet (No. ESU-3355).

(e.g. LTWT-115A0-R/T/X2)

Refer to standard specification pages.

SPECIFICATION CHANGES

■ Input specifications

• Available input range: Refer to the table shown right.

■ PERFORMANCE

Accuracy (including influence from temperature and

frequency): Refer to the table shown right.

e.g. 3-phase / 3-wire, 100 V, 5 A

Input range: -350 - +350 W

As input span is 35 % for std. range (-1000 - +1000 W),

accuracy is ±0.8 %.
