FEATURES

1. Compact to save panel space

The 24 × 48 mm hour meters are just half the DIN 48 × 48 stan­dard size. They help save the panel space.

2. Reset button

The hour meters can be reset to zero (TH64).

3. Wide-ranging measurement display

The measurement can be displayed from 0.1 hour up to

99999.9 hours (TH63). The dial size is the same as that of 48 ×
48 DIN size hour meters (TH14 and TH24 series).

4. Easy to install

The flat terminals (#187) are used for easier wiring. There is no
need to undo the lock spring.

5. High-performance sync motor with 50/60 Hz selector

The noise-resistant, accurately turning motor is employed to
provide for longer period of measurement. The power frequency
can be selected for 50 or 60 Hz.

6. Rotary indicator

NAiS’s original moire pattern mechanism helps watch the rotary
indicator for quick monitoring (one turn every 72 seconds).

7. CE marking

The hour meters satisfy EMC directives (EN50081-2/
EN50082-2) and low-voltage directives (EN61010-1).

TYPICAL APPLICATIONS

Management of small generators and food processing
machines; hour counting for leased equipment; maintenance
management of various equipment, etc.
