JH Technology power supply modules provide regulated and filtered
DC supplies. Model JH9046 provides two adjustable voltage range
options: 1.5 to 15V at 100mA max. load or 15 to 30V at 50mA. If
specified on your order, the factory will adjust the output to your
requirements.
JH9246 is a dual-output model designed with 4/20mA 2-wire
transmitter loops in mind. Each module is capable of powering two
such loops. Its two 24V outputs are isolated from each other,
minimizing ground-loop concerns in multi-loop applications.
All three models are internally protected against failure due to
short circuits. 115 and 230Vac power options are available.
ORDERING INFORMATION
| Model
JH9046-1 |
Normally
factory-set at 5Vdc, If you prefer different settings,
please specify on your order and the factory will do it at
no extra charge. Also specify on your order if you require
a 115VAC or 230VAC input source. |
| Model
JH9046-2 |
Normally
factory-set at 24Vdc. If you prefer different
settings, please specify on your order and the factory
will do it at no extra charge. Also specify on your order
if you require a 115VAC or 230VAC input source. |
| Model
JH9246 |
Nonadjustable Output Fixed at 24Vdc (+/-4%). Specify on
your order if you require a 115VAC or 230VAC input source.

INSTALLATION AND CONNECTIONS
These power supplies plug into any standard
8-pin circular ("octal") relay socket. JH Technology
offers two sockets: DS008 for DIN-rail or surface mounting and ST008
for Snap-TrackŪ mounting (see the Accessories
page).
Pin connections are:
Pin 1: AC Power
Pin 2: No connection
Pin 3: AC Power
Pin 4: No connection
Pin 5: Output (+) Positive, Second
Supply* (JH9246 Only)
Pin 6: Output (-) Negative, Second
Supply* (JH9246 Only)
Pin 7: Output (+) Positive
Pin 8: Output (-) Negative
(*) Notes: The "Second Supply" at
Pins 5 & 6 are available on the Model JH9246 only. For the
JH9046-1 and JH9046-2 there are no connections to Pins 5 & 6.
