The LPIT (Low Power Instrument Transformer) Adaptor is a signal converter that can receive the LLV (0-8V) signal from the test device, and convert it into voltage signals that are suitable for the conditions of IEC61869-10 (LPCT) and IEC61869-11 (LPVT) standards.
It enables you to test protection and measurement devices that have low level inputs for voltage and current sensors with the KINGSINE protection relay test set.
4 channels of LPCT and 4 channels of LPVT output (RJ45 interface).
Supports both single-ended and differential programable control.
Meeting the IEC 61869-10/11 standard.
Can be used in conjunction with KINGSINE KFA320,KFA310, KF86P protection relay testing devices and other equipments.
Compatible with devices from other companies that have a Low-Level signal output of 0~8V.
| Analog Input | Channels | Input Range | Remark |
| Voltage | V1 ~ V4 | 0-8V | LPVT |
| Current | I1 ~ I4 | 0-8V | LPCT |
LPlT output that supports all typical sensor types according lEC61869:
Rogowski coil and inductive low-power sensor for current
R-divider and C-divider for voltage
