Basic PDU
Straightforward power distribution
Distributes power to server, network and control cabinets with no metering electronics in the way. Extruded aluminium chassis with a black powder coat and a solid copper busbar, so one failed outlet does not take the rest of the strip down. Horizontal or vertical mounting, with surge protection, breakers, fuses and USB / Type-C modules available on request.
Key advantages
- Continuous copper busbar — a failed outlet does not cut the others
- Mixed socket standards on one chassis: UK, Schuko, NEMA, IEC C13 / C19
- Optional 10–40 kA surge modules, breakers and fuses
- Single-phase AC, three-phase AC and 240 V / 336 V HVDC versions

Metered PDU
See what each rack actually draws
The same chassis with measurement built in. An LCD on the unit shows voltage, current, active power, frequency, power factor and accumulated energy, so racks can be loaded to their real limit instead of a guess. RS485 (Modbus-RTU) feeds the same figures to your monitoring system, and the meter module is hot-swappable — it can be replaced without dropping power to the outlets.
Key advantages
- Local LCD readout: V, A, kW, Hz, PF and kWh
- ±1% accuracy on voltage, current, power and energy
- RS485 Modbus-RTU into your DCIM or BMS
- Hot-swappable meter — no downtime to service it

Smart PDU
Per-outlet visibility and remote control
Measures and switches every outlet individually. A flush-mounted controller (1 × LAN, 2 × RS485, 1 × temperature/humidity) handles local and remote management and hot-swaps out without powering down the rack. Four series — A, B, C and D — let you pay only for the level of metering and control you actually need.
Key advantages
- Per-outlet metering and remote on/off switching
- Alarm thresholds per branch for early warning
- SNMP v1/v2c/v3, Modbus TCP/RTU, MQTT, SSHv2, HTTPS, IPv6
- Daisy-chain with metered units to save ports and cost
Smart iPDU — A / B / C / D series

All four series include full-circuit and per-phase metering, ±1% accuracy, a temperature/humidity sensor, LCD, dual RS485 (Modbus) and 10/100 Ethernet. They differ only in per-outlet metering and per-outlet control.
Supported protocols
- SNMP v1/v2c/v3
- Modbus TCP/RTU
- MQTT / MQTTS
- HTTP / HTTPS
- SSHv2
- IPv4 / IPv6
- DHCP
- DNS
- NTP
- Syslog
- SMTP / SMTPS
- TLS v1.2
STS / ATS
Dual-feed redundancy for critical loads
A single-pole transfer switch sitting between two independent AC feeds. If one source drifts out of tolerance or fails, the load moves to the other one fast enough that connected equipment never sees an interruption. Fully digital DSP control with redundant auxiliary supplies, and an optional SNMP card for remote monitoring.
Key advantages
- Two-stage transfer: < 6 ms typical, < 11 ms maximum
- Fully digital DSP control with redundant auxiliary power
- 10 A, 16 A and 32 A capacities, 1Φ + N + PE
- Optional SNMP card for remote management
