350W Portable Emergency Power Station 288Wh LiFePO4 Security Cabinet Backup EPS 10ms Transfer PL350

Network and security equipment fails quietly: a router reboots, an NVR loses its recording window, an access controller drops the door schedule. PL350 is arranged for that job rather than for camping. It sits on a shelf near the cabinet, passes the load through while mains is present, and switches to battery in under 10 milliseconds when the supply drops, which is short enough for most routers, switches, NVRs and access controllers to ride through without restarting.

What it protects, and for how long

A typical small installation draws 30W to 80W: a router, a PoE switch, one or two cameras and an NVR. Against 288Wh of usable LiFePO4 capacity that is roughly three to six hours of runtime, enough to cover the short outages that cause most recording gaps and door faults, and enough time to bring a generator or a manual procedure into play for a longer one.

The output side is deliberately mixed. AC outlets carry the power adapters, the 12.8V 10A DC socket can feed a 12V camera or a small switch directly without an adapter, two USB-C ports handle a tablet or a 4G dongle, and the 18W USB-A port covers a phone. Total draw has to stay inside 350W continuous, with 600W available briefly for devices that surge at start-up.

For installation, the cabinet measures 242 x 224 x 150mm and weighs 4.15kg, so it can be wall-shelf mounted or left on the floor of a comms cupboard. Charging is 200W from mains, which brings the unit back to full in about two and a half hours, and a 240W solar input covers sites where mains is unreliable or absent altogether, such as remote gates and container offices.

PL350 is supplied in a colour box with foam inserts and an export carton, carries a 3 year warranty, and ships with a choice of seven outlet standards for integrators working across regions.

Factory and quality behind each PL350

PL350 is assembled at the SOUOP plant in Guangdong, where cell sorting, pack welding, BMS programming, inverter assembly and ageing tests are all handled on site rather than outsourced. The facility runs ISO 9001 quality management and BSCI social compliance audits and employs a dedicated reliability lab for drop, vibration and thermal cycling tests.

Every unit is cycled through charge, discharge, load and insulation checks before packing, and each pack carries a serial number tied to its cell batch, so a distributor can trace a warranty claim back to the production run. Certificates for CE, FCC, RoHS, PSE and UN38.3 transport testing are held on file and can be supplied with each order.

For buyers who need their own version, the outlet block, enclosure colour, silkscreen, manual language and packaging artwork can all be changed, and the BMS parameters can be re-tuned for a specific market. Standard production runs take 10 to 20 working days after payment, with samples available before an order is placed.
