Product Highlights
Three isolated 0–30 A elements support 1-, 2-, or 3-element testing using the closed-link method. For open-link testing, the elements combine into one output of up to 90 A with the optional open-link harness.
Simple front-panel controls set the supply voltage, test current tap, power factor, and elements, so technicians get repeatable results from one test to the next.
A breaker switch powers the unit and replaces fuses. It trips on a misconnection or when draw exceeds 5 A, and resets once the wiring is corrected.
An LED histogram shows the output from 80% to 120% of the tap setting, with two LEDs lit at 100%, so the technician can see the test current is on target.
Features
- Built for your reference standard: RADIAN RX-10, RX-11, or RX-15; RD-20, RD-21, or RD-23; or RM-10 or RM-11 (a separate build for each).
- Three isolated 0–30 A current elements for 1-, 2-, or 3-element testing; open-link output up to 90 A with the optional harness.
- Switch-selectable test voltage: 69, 120, 208, 240, 277, and 480 V, 60 Hz.
- Full load, power factor, and light load current taps, with switch-selectable power factor of 1.0 or 0.5 lag.
- Closed-link and open-link phantom loading, with element selection of A, B, C, AB, AC, BC, or ABC (closed-link) and X1, X2, or X3 (open-link).
- Breaker-based protection with no fuses: trips on a misconnection or when draw exceeds 5 A, then resets.
- Weatherproof, high-impact case; 25 lb with the reference standard installed (14.95 × 12.13 × 9.58 in).
Portable Meter Test Kit
- Connect the test cable to the meter installation and set the supply voltage to match the service.
- Set the test current tap to the meter’s test amperes (TA) and select the elements to include.
- Run the test points: full load, power factor (0.5 lag), and light load. The LED histogram confirms the current is on target.
- Read the results on the reference standard, or use the RADIAN RM-111 Automated Comparator to calculate and store percent registration or percent error.
UTEC 430 Test Currents and Voltages
Test voltage is switch-selectable at 69, 120, 208, 240, 277, and 480 V, 60 Hz. Each tap sets the full load and power factor current, with light load at one-tenth of that value.
Taps marked with an asterisk require the optional 50 A or 90 A open-link harness.
| Full load and power factor | Light load |
|---|---|
| 2.5 A | 0.25 A |
| 5 A | 0.5 A |
| 10 A | 1 A |
| 15 A | 1.5 A |
| 20 A* | 2 A* |
| 30 A | 3 A |
| 60 A* | 6 A* |
| 90 A* | 9 A* |
UTEC 430 FAQ
What can the UTEC 430 test
The UTEC 430 tests solid-state and induction meters, single-phase or polyphase, self-contained or transformer-rated. It can also test electronic or mechanical standards and Test Boards.
What is phantom load testing
In phantom load testing, the test kit supplies the test voltage and test current from separate sources rather than drawing real load through the meter. That lets a technician test a meter at full load, power factor, and light load at the site, whatever the customer's load is at the time.
What is the difference between closed-link and open-link testing
Closed-link testing uses the three isolated 0–30 A elements, with the meter's voltage clips closed during the test. Open-link testing combines the elements into one output of up to 90 A using the optional open-link harness, with X1, X2, or X3 multipliers.
Which reference standards work with the UTEC 430
The UTEC 430 supports the RADIAN RX-10, RX-11, and RX-15, the RD-20, RD-21, and RD-23, and the RM-10 and RM-11. Each standard uses a different build of the 430, so tell us which standard you have, or plan to use, when you request a quote. Add the RADIAN RM-111 Automated Comparator to calculate, display, and store results in percent registration or percent error.
How is the UTEC 430 protected and supported
A breaker switch replaces fuses and trips on a misconnection or when draw exceeds 5 A. The kit carries a two-year warranty, and RADIAN Care Plans extend coverage.
