UMD PSU-22 2 V4.0
Safety
Installation.
Unless otherwise stated TSL equipment may be installed at any angle or position within an operating
temperature range of 5°~ 25°C .
The RJ45 connectors are for use only with TSL UMD equipment.
All TSL equipment conforms to the EC Low Voltage Directive:
EC Low Voltage Directive (73/23/EEC)(OJ L76 26.3.73)(LVD).
Amendment: (93/68/EEC) (OJ L220 30.8.93).
Earthing/Grounding
In all cases, the frame of the equipment must be earthed on installation. Connection to an earthed strip
running the length of the frame is ideal.
The earth pin on the IEC mains inlet connector is connected to the metal frame of the equipment, to 0
volts on the internal DC PSU and to signal ground, unless otherwise stated. All metal panels are
bonded together. Rack mounted equipment must be earthed (grounded).
Mounting
Careful consideration of the of equipment location and mounting in racks must be made. In particular,
consideration must be given to the stability of free-standing racks by mounting heavy equipment low in
the rack. The rear of the unit should be supported in the rack.
Power
For pluggable equipment, the socket outlet shall be installed near the equipment and shall be easily
accessible.
Consideration must be given to the supply circuit loading and switch on/fault surges that will affect
overcurrent protection trips and switches etc.
Check that the fuse rating is correct for the local power (mains) supply. Replacement fuses must be of
the same rating and type for continued protection against fire risk.
The equipment rating is shown on the rear panel.
No power supply cord is provided with this equipment.
Do not switch on until all connections are made.
Ventilation
Due consideration for cooling requirements must be given when mounting the equipment. Ideally 1RU
of rack space should be left above and below the unit.
If the equipment is installed in a closed unit, consideration must be given to providing forced air cooling
in order that the maximum recommended temperature is not exceeded.

UMD PSU-22 6 V4.0
1.0 Installation
Unless otherwise stated TSL equipment may be installed at any angle or position within a
recommended operating temperature range of 5°~ 25°C .
Good installation practice should be adhered to for the cooling requirements of this unit. Ideally, allow
1RU of space between this unit and adjacent units.
For pluggable equipment, the socket outlet should be installed near the equipment and should be
easily accessible.
For continued protection against risk of fire, all components must be replaced with similarly rated
components.
In all cases the case of the equipment should be earthed on installation. A threaded stud is provided
for this purpose.
Do not switch on until all connections are made.
2.0 Description
The PSU-22 is a 19” 2RU unit which provides 240 Watts of power, mnemonic and serial tally
distribution for typically up to a maximum of 96 S8C / D8C displays.
The unit may be ordered or upgraded with a second 240 Watt PSU which will provide 100%
redundancy in the event of an internal power supply module unit failure. This upgrade is a
straightforward plug in upgrade. The frame is fully wired to accept a second PSU.
Single PSU units have the PSU (PSU1) fitted to the LH frame and the top IEC is the power inlet
connector.
This unit can provide a maximum of 96 PLU (power loading units) where one PLU is equivalent to 2.5
Watts. Note that a maximum of 240 Watts only may be drawn from the PSU-22.
In the standard, non dual-redundant unit, power (at +24V) is provided by one auto-ranging PSU (88 ~
264V, 47/63 Hz) via a diode bridge arrangement output (to isolate the second optional PSU module)
and re-settable internal fuse to the rear distribution board.
Each of the 48 RJ45 o/p connectors is rated at a maximum of 1.1Amps*( the re-settable fuse opens at
about 1.5A after approx. 90 secs).
The front LEDs from the top down indicate:
Module A (LH module)
Module B (RH module)
+24VDC Rail
Serial 1 (Green when active, amber when serial data present but not used).
Serial 2 (Green when active, amber when serial data present but not used).
Once an input signal is detected by the unit that signal will continue to be used until it fails or is
intentionally removed. The circuit is noise immune so there will be a short delay before the circuit
switches from one input to the other.
An auxiliary +24V unregulated supply, fused at 1.8 Amps, is available on the rear panel. This power is
included in the overall 240 Watts available from the internal PSU block(s).
*Do not exceed the rating of the unit of 96 PLU or 240 W otherwise an internal, re-settable fuse will
open.

UMD PSU-22 7 V4.0
3.0 Operation
The PSU-22 can be used either:
1. As a stand alone unit. For example, in a monitor stack with dynamic displays or static displays
not requiring serial tally information, but where the silence detection data from Audio
Monitoring Units needs to be passed to an alarm monitoring system such as the TSL AMS-1,
or, more usually.
2. As a single or one of several local power supplies of a larger system where the displays are
controlled by a TallyMan Controller, TM1.
The input RJ45 serial port on the rear of the PSU-22 is fed from any TM1 Display Port which could be
located at some distance away (up to 200m) from the monitor stack.

UMD PSU-22 11 V4.0
7.0 General Notes
1. It is recommended that the 0v/chassis connections are all connected together externally.
2. Allow 1RU above and below the unit for ventilation.
3. Do not exceed the maximum PSU-22 rating of 240W. This rating takes into account the internal
temperature rise limitations and is a safe maximum rating. Each RJ45 connector can supply up
to about 1.1A at +24V. This is to allow products such as the ML1 (which draws approx 800mA)
to be powered along with a combination of the standard displays up to a maximum of 240W.
4. For RJ 45 connected TSL equipment, the pin-out is 1:1.
5. The RJ 45 connectors must only be used to connect TSL UMD equipment together.
6. It is recommended that Category 5E FTP (foil screened twisted pair) cable is used. The
individual cores are rated at 1A at 24volts. Two cores are use for each power rail.
7. Each RJ45 output connector is individually buffered for both power and data from the others.
8. One PLU (Power Loading Unit) ≡2.5Watts
