| Input Power |
100 to 240 V (± 10 %) AC, 1 Ø, 50/60 Hz, 700 VA |
| Outputs |
All outputs are independent of sudden changes in line voltage and frequency. This provides stable outputs not affected by sudden changes in the main source. All outputs are regulated so changes in load impedance do not affect the output. |
| Output Current |
Output power ratings are specified in AC RMS values and peak power ratings.

| Timer |
The timer-monitor input is designed to monitor and time-tag inputs, as a ‘sequence of events’ recorder. In addition, the binary input controls enable the user to perform logic AND/OR functions and conditionally control the binary output relay to simulate circuit breaker, trip, reclose, and carrier control operations in real-time. The timer function displays in seconds or cycles, with the following range and resolution:
| Seconds: |
0.0001 to 99999.9 (auto-ranging) |

|
| Binary Input - Start/Stop/Monitor Gate |
To monitor the operation of relay contacts or trip SCR, a continuity light is provided for the input gate. Upon sensing continuity, the lamp will glow. In addition to serving as wet/dry contacts the binary inputs may be programmed to trigger binary output sequence(s).
| Input rating: |
Up to 300 V AC/DC |
|
| Binary Output Relays |
SMRT1 has an independent, galvanically isolated, output relay contact to accurately simulate relay or power system inputs to completely test relays removed from the power system. The binary output simulates normally open/normally closed contacts for testing breaker failure schemes. The binary output can be configured to change state based on binary input logic.

| Metering |
Measured output quantities such as AC Amperes, AC Volts, DC Volts, or DC Amperes, and time may be simultaneously displayed on the large, colour TFT LCD touch screen of the STVI. The AC and DC outputs display the approximate voltage/current output before the initiation of the outputs. Accuracies are specified from 10 to 100 % of range, 25 °C ± 5 °C, 50-60 Hz. |
