Delta's Composite V-A-W Meters, for the last
15 years, have been acclaimed as the most successful electrical
testing equipment in India. Their number in thousands in the
field for umpteen types of different applications speak for
itself. Now two new features have been added with dual microcontrollers
at the heart
Line Frequency and PF :
A push-button on the front dial changes the display from
V-A-W to PF-Hz-W.
Optically Isolated RS-232 Interface :
A galvanically isolated RS-232 port is provided
to communicate with a PC; the PC displays/stores the captured
parameters |

Specifications |
|
| |
Dimensions : 290 mmW × 55mmH ×
180mmD |
| Panel Cut-Out : 284mmW × 48mmH |
| Enclosure : Black-Painted Mild Steel Box |
| Aux. Supply : 200-250VAC @ 8VA. |
| Displays : 31/2 DIGITS, 0.5 LEDs (3 sets) |
| Accuracy : Class:0.5 (for V,A,W), Class:0.1
for Hz, Class:1.0 for PF (due to computation limits of µc ;
this error becomes less than Class:0.5 on the PC Screen) |
| Frequency Response : 10Hz-10kHz (all displays) |
| PF Range : 0.1 (LAG) - 1.0 - 0.1 (lead) |
Connections :
1. Aux. supply by barrier terminals on the rear
2. Load supply/load terminal of 4mm 0 - 15A rating on the front dial
( rear connections only against
specific request) |

a. When using DT-2000(232),
if frequent heavy starting surge currents are encountered, the use
of external
CT operated models, for more reliable operations, is suggested |
| |
b. For custom-built models, send enquiries
with your specific requirements |
Protection |
| |
1. The aux. supply to the instrument is
protected by a surge-suppressor against line surges. However inductive
loads such as a contractor-coil, heavy-duty transformers, etc .should
not be connected across the same supply. |
| |
2. The voltage sensing circuit is protected
by a heavy-duty metal-oxide varistor of 500V rating connected across
the load terminals. Hence the load supply should not exceed 500VAC. |
| |
3. The current sensing shunt is protected
by a replaceable glass-cartridge fuse on the rear of the instrument.
This glass cartridge fuse should not be replaced by fuse of higher
ratings or wire shorts. Otherwise the instrument may get damaged. |
