The PJ Open Frame series offers varieties of nominal output voltage with versatile configuration options as follows.
C - Enclosed
L - L Frame
B - Open Frame (Bareboard)
The MEG configurable power supply is designed for use in both medical and industrial applications. It supports up to 6 isolated output. The products can be configured for output voltages ranging from 2Vdc to 60Vdc.
Power Boost is a reserve power which is available constantly, to allow reliable startups supporting sudden and short spikes of loads with high inrush currents, typically during turn on to remove the need of more expensive higher rated power supply units. After the output has reached its steady state set value, the power supply can support surge loads with a higher short-term power demand up to 150% of maximum rated load (IO Max), for a maximum duration of 5 seconds. The Power Boost is available repetitively, provided that the average output power (R.M.S) shall not exceed the continuous maximum operating condition. See duty cycle calculation below.

It is not recommended to extend the duration of Power Boost to be longer than the specified duty cycle calculation, this may cause damage to the PSU.
Advanced Power Boost (APB)
With multiple loads connected in a system, a large outrush current could be drawn (demanded) due to one fault load. This will be detected by APB. The APB will trip the circuit breaker (circuit breaker with appropriate rating based on the system load) on the current path of the fault load due to high current. This thus prevents the system from shutting down while the other connected current paths continue to operate without interruption.
The following waveforms demonstrate the typical output voltage and output current when APB is activated :
