PowerSync Analyzer

Sifos Technologies offers the PowerSync® Analyzer in two form factors: The multi-slot PSA-3000 and the compact PSA-3402. Both PSE test instruments support the world’s most comprehensive and automated PSE Conformance Test Suites covering PSE’s that power up to 30W on 2-pairs and up to 90W on 4-pairs. 


Connects up to 24 PSE ports and provides access to the PSE  Conformance Test Suite, the Multi-Port Suite, and LLDP Emulation and Analysis.


Compact and transportable configuration supporting PSE Conformance Test Suite and LLDP Emulation and Analysis options.

Key Features

PSA-3000 / PSL-3000 Software

Included with every PSE test instrument in the PSA-3000 family are PSA Interactive (GUI) and PowerShell PSA (script automation) software. Whether running test suites, setting up PD emulations, analyzing specific PSE behaviors, or automating QA tests, PSA Software enables high productivity and rapid results.

PowerShell PSA Software

PSE Conformance Test Suites

Whether testing single port injectors or 48 port PSE’s, Sifos offers the ultimate solution to assess PSE conformance to all applicable IEEE specifications. With the click of a button, fully automated testing and reporting delivers comprehensive and informative results including difficult-to-spot intermittent conformance behaviors.   Available to PSA-3000 and PSA-3402 PSE test instruments.

PowerSync Programmable Loads (PSL-3424, PSL-3000)

The PSL-3424 is Sifos’ newest member to the PSA-3000 family of PSE test instruments.   It uniquely offers capability to continuously load up to 24 4-Pair, 100 watt capable PSE ports simultaneously.  It also introduces new testing features not previously available in the PSL-3000 Programmable Load.

The PSL-3000 is Sifos’ lowest cost-per-port solution for PSE loading and testing.   It supports the 2-Pair Multi-Port Suite including the 2-Pair Multi-Port Test Suite for automated PSE system and power management analysis.  It can provide continuous 99W loading on up to 12 802.3bt PSE ports simultaneously.

Both instruments are managed using PSA Interactive and PowerShell PSA software environments and, like the PSA-3000, both instruments are fully certified to industry safety and emissions standards.

Power Management Analyzer Suites

While most PSE ports are part of multi-port PSE, behaviors of such systems of PSE ports are beyond the scope of IEEE 802.3 specifications.  Sifos offers two fully automated analyzer suites that uniquely characterize PSE port administration and power management behaviors including PD admittance policies, PSE capacity management, LLDP policies, and powering stability.   Each of these suites are built upon Live PD Emulation, a feature that enables each test port to independently and continuously emulate user-described PD’s.

LLDP Emulation and Analysis

The optional LLDP Emulation feature allows a PSA-3000, PSL-3424L, or PSL-3000 test port to behave just like an 802.3at or 802.3bt PD that uses LLDP to convey its power demands.  802.3 PoE LLDP is a special variant of LLDP protocol that involves handshakes and protocol timing between a PSE and a PD.

Rapid PSE and Chained Data Test of 4-Pair and 2-Pair PSE's

The optional PSL-3424-QT feature license opens up two important productivity tools in the PSL-3424 platform.  PSL-3424 Quick Test is a fully automated PSE functional test covering between 2 and 8 PSE ports in a test cycle with average test times on the order of 10 seconds per port tested.   The Chained Data Test user interface allows rapid construction and verification of test setups used in “snaked data path” testing of PSE’s with user specified loads and optional LLDP power negotiation on each test port.
