3 Functional description

PSH150 includes a 1 phase SMPS module with PFC and class II wiring. A converter located on the
secondary side allows the supply of a programmable voltage (5 to 55V), with user settable current
limitation. The output is provided with an active ORing circuit that allows the parallel connection for
redundancy of several units without the need of an external redundancy module.
An auxiliary power supply of 12V/100mA is available.
An external INHIBIT signal can be applied for controlling the output status.
A multifunctional display shows the output parameters and 3 keys can be used for programming the
unit. A dry contact (relay) is related to “DC-OK” status.
RS485 and USB ports are available for remote monitoring and setup.

3.1 Main DC output

PSH150 provides a DC output programmable from 5Vdc to 55Vdc with up to 12A output current and a
maximum output power of 150W. The maximum output current varies according to the programmed
output voltage and to the ambient temperature; in Figure 3 and Figure 4 the current and power
derating curves are reported.

The output is short circuit protected; in case of an output short circuit the output is switched off and an
hiccup cycle is started. A “short circuit” alarm code is reported on the display (§3.4.3).

PSH150 user manual rev4

Page 8/15

3.2 Auxiliary 12V output

PSH150 is provided with an auxiliary regulated 12V output with up to 100mA current capacity. This
output is short circuit protected. The auxiliary output shares the same ground (negative terminal) with
the main DC output.

3.3 INHIBIT input

An opto-isolated input allows switching off the main DC output. The polarity of the input can be
defined using the “inhibit polarity” (POL) field (§3.4.2). The controlling signal must have a voltage
between 5Vdc and 30Vdc. The auxiliary 12V output is always active and can not been switched off.

3.4 Display interface

The PSH150 is provided with a 3-digits 7-segments LED display used to indicate the status and to
navigate through the configuration menus. During normal operation, the output parameters are
reported (§3.4.1). Alarms and error codes are also reported on the display (§3.4.3)

3.4.1 Normal operation

During normal operation the output voltage, current and power are reported on the display. 2 green
LEDs indicate which measurement is currently shown. Every parameter is visible for 3 seconds, then
the next measurement is shown.

3.5 Parallel connection

Multiple PSH150 can be connected with the output in parallel for power increase and / or redundancy.
In this mode of operation, the field “operating mode” (OP) shall be set to “Parallel” (PA).
The unit integrates an internal ORing circuit allowing paralleling several units for redundancy.
For proper operation the cable length connecting the PSH150 outputs to the load must have the same
length and cross-section. For optimal current sharing it may be necessary to slightly adjust one of the
two devices output voltage until the same current is delivered by the two units. It is recommended to
limit the load power to 80% of the sum of the individual output power of the paralleled units.
