Caution warns you of a potential hazard. If you do not read
and follow instructions carefully at this point, the product
could be dama ged or important data could be l ost.
Note highlights important information on using the product.
Product Related Safety Precautions
WHP25 Mains Power Supply delivered to you has been
tested for safety and approved as shipped from the factory.
Note the following precautions:
Ground the product, and verify outdoor installation
grounding periodically to minimize shock hazard.
CAUTION
Do not modify the unit. Improper modificatio n can damage
the product o r lead to malfunction.
ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent
damage to electronic circuits. Vaisala products are
adequately protected agains t ESD for their intended use.
However, it is possible to dam a ge the produ ct by deliver i ng
electrostatic discharges when touching, removing, or
inserting any objects inside the equipment housing.
To make sure you are not delivering high static voltages
yourself:
VAISALA___________________________________________________________5
Page 8
User's Guide ________________________________________________________
- Handle ESD sensitive components on a properly
grounded and protected ESD w orkbench. When this is
not possible, ground yourse lf to the equipment chassis
before touching the boards. Ground yourself with a wrist
strap and a resistive connection cord. When neither of the
above is possible, touch a cond uctive part of the
equipment chassi s with y our other ha nd befo re to uc hin g
the boards.
- Always hold the boards by the edges and avoid touching
the component contacts.
Warranty
For certain prod ucts Vaisala n ormally gives a l imited one

PRODUCT OVERVIEW
This chapter introduces the WHP25 Mains Power Supply
features.
Introduction to WHP25 Mains Power Supply
WHP25 is a compact AC (Mains) Power Supply Unit
intended for outdoor use. The unit is capable of delivering
power, for exam ple, to the WA25 Wind Set.
The nominal inpu t power of 230 VAC can be changed by
jumpers between 100 VAC and 245 VAC (±10 %). The
WHP25 unit provides two power outputs, namely 24.0 VDC
(max 5.2 A) and 38.0 VAC (max 0.9 A).
The WHP25 unit has a waterproof housing made from cast
aluminum. The mounting hardware is included in the
delivery. It is mountable to a Ø 100 mm standard pole mast.

INSTALLATION
This chapter provides y ou with in formation that is intend ed
to help you install WHP25 Mains Power Supply.
Installation Procedure
Before installation, route the input (AC) power cable near
the mast, which WHP25 Mains Power Supply will be
mounted to. Make sure you selected a pole mast w ith a
diameter from 99 to 105 mm for in stallation with the
standard mounting clam p.
To install the WHP25 unit, follow the procedure below.
1. Remove the four screws holding the cover of the
WHP25 unit. Remove the cover.
2. Attach the unit to the mast at a suitable place with the
provided accessories and the standard mounting clamp.
Refer to Figure 2 on page 10.

3. If the local voltage level is other than 230 VAC,
reselect the voltage with the X2 and X3 jumpers
located inside the WHP25 unit. For the location of the
jumpers, refer to Figure 3 on page 11. For instructions
how to set the jumpers for different input voltages,
refer to Figure 4 on page 11.
Improper jumper setting damages WHP25 Mains Power
Supply.
CAUTION
Observe the instructions and warnings in the instruction
label inside the unit, refer to Figure 4 on page 11.
