For power supplies using 208/230 volt, then the circuit breakers must have a minimum of 50 amps. The unit is delivered with a 460 volt cable and an ISO standard CEE power plug (59 feet/18 meters). The 230 volt cable does not have a power plug. The refrigerated container must be protected from electrical power surges.
Can a 208/230 volt power supply run on 50 Hz?
Some units are available with three phase 208/230 volt transformers. Units are available to run on 50 or 60 Hz. The power supply must be grounded and have circuit breakers with a minimum of 30 amps. For power supplies using 208/230 volt, then the circuit breakers must have a minimum of 50 amps.
How many power supplies can be mounted in a 40ft container?
Power supplies <300kW can be mounted in only a single 40ft container, while greater powers can be achieved in multiple containers and connected upon delivery. Depending upon specifications, containerized power supplies may be stacked, or located side-by-side. Setup and testing or shut-down and packing can be achieved within a matter of days.
Why does a container need a lot of power?
Older containers or those with degraded insulation may suffer from increased heat transfer, subsequently leading to more power usage. Furthermore, these containers often require frequent defrost cycles which again contribute to additional energy drain. The type of cargo being transported influences power requirements as well.
Do reefer containers need a power supply?
It's all about the power supply. Reefer containers require an external power source to run their cooling (or heating) systems. Typically, this power comes from the ship or truck carrying them or from an onshore electrical grid when in port or storage.
Are power supplies weatherproof?
The entire system is made to be entirely weatherproof. Power supplies <300kW can be mounted in only a single 40ft container, while greater powers can be achieved in multiple containers and connected upon delivery. Depending upon specifications, containerized power supplies may be stacked, or located side-by-side.
